LISA-U series - System Integration Manual 1.5 Power management 1.5.1 Power supply circuit overview LISA-U series modules feature a power management concept optimized for the most efficient use of supplied power. This is achieved by hardware design utilizing a power efficient circuit topology (Figure 4), and by power management software controlling the module’s power saving mode.
LISA-U series - System Integration Manual The VCC pins are directly connected to the RF power amplifiers and to the integrated Power Management Unit (PMU) within the module: all supply voltages needed by the module are generated from the VCC supply by integrated voltage regulators. V_BCKP is the Real Time Clock (RTC) supply. When the VCC voltage is within the valid operating range, the internal PMU supplies the Real Time Clock and the same supply voltage will be available to the V_BCKP pin.
LISA-U series - System Integration Manual When LISA-U series modules are in operation, the voltage provided to VCC pins can go outside the normal operating range limits but must be within the extended operating range limits specified in LISA-U1 series Data Sheet [1] and LISA-U2 series Data Sheet [2]. Occasional deviations from the ETSI specifications may occur when the input voltage at VCC pins is outside the normal operating range and is within the extended operating range.
LISA-U series - System Integration Manual The voltage at the VCC pins must ramp from 2.5 V to 3.2 V within 1 ms. This VCC slope allows a proper switch on of the module when the voltage rises to the VCC normal operating range from a voltage of less than 2.25 V. If the external supply circuit cannot raise the VCC voltage from 2.5 V to 3.
LISA-U series - System Integration Manual The following sections highlight some design aspects for each of the supplies listed above. Switching regulator The characteristics of the switching regulator connected to VCC pins should meet the following requirements: Power capability: the switching regulator with its output circuit must be capable of providing a voltage value to the VCC pins within the specified operating range and must be capable of delivering 2.

LISA-U series - System Integration Manual 2 Design-In 2.1 Design-in checklist This section provides a design-in checklist. 2.1.1 Schematic checklist The following are the most important points for a simple schematic check: DC supply must provide a nominal voltage at VCC pin above the minimum operating range limit. VCC supply should be clean, with very low ripple/noise: suggested passive filtering parts can be inserted.
LISA-U series - System Integration Manual 2.1.2 Layout checklist The following are the most important points for a simple layout check: Check 50 nominal characteristic impedance of the RF transmission line connected to the ANT pad (main RF input/output) and to the ANT_DIV pad (RF input for Rx diversity). Follow the recommendations of the antenna producer for correct antenna installation and deployment (PCB layout and matching circuitry).
LISA-U series - System Integration Manual 2.2 Design Guidelines for Layout The following design guidelines must be met for optimal integration of LISA-U series modules on the final application board. 2.2.
LISA-U series - System Integration Manual Rank Layout Remarks ANT Very Important RF input for Rx diversity ANT_DIV Very Important Design for 50 characteristic impedance. See section 2.2.1.1 Design for 50 characteristic impedance. See section 2.2.1.
LISA-U series - System Integration Manual Add GND keep-out (i.e. clearance) on buried metal layers below ANT and ANT_DIV pads and below any other pad of component present on the RF line, if top-layer to buried layer dielectric thickness is below 200 µm, to reduce parasitic capacitance to ground (see Figure 55 for the description of the GND keep-out area below ANT and ANT_DIV pads) The transmission line up to antenna connector or pad may be a micro strip or a stripline.

The Layer 4 (bottom layer, described in Figure 59) is designed for signals routing, components placement and GND plane. Layer 4 thickness is 0.035 mm.
LISA-U series - System Integration Manual The use of standard SMA type connector is not permitted, as its standard usage allows easy replacement of the attached antenna. However RP-SMA (Reverse-Polarized-SMA) connector type fulfills the minimum requirements to prevent exchangeability of antenna on the reference design. 2.2.1.2 Main DC supply connection The DC supply of LISA-U series modules is very important for the overall performance and functionality of the integrated product.
LISA-U series - System Integration Manual 2.2.1.3 USB signal The LISA-U series modules include a high-speed USB 2.0 compliant interface with a maximum throughput of 480 Mb/s (see Section 1.9.3). Signals USB_D+ / USB_D- carry the USB serial data and signaling. The lines are used in single ended mode for relatively low speed signaling handshake, as well as in differential mode for fast signaling and data transfer. Characteristic impedance of USB_D+ / USB_D- lines is specified by USB standard.
LISA-U series - System Integration Manual If DC decoupling is required, a large capacitor needs to be used, typically in the microFarad range, depending on the load impedance, in order to not increase the lower cut-off frequency of its High-Pass RC filter response 2.2.1.5 Module grounding Good connection of the module with application board solid ground layer is required for correct RF performance. It significantly reduces EMC issues and provides a thermal heat sink for the module.
LISA-U series - System Integration Manual 2.2.1.8 Digital pins and supplies External Reset (RESET_N): input for external reset, a logic low voltage will reset the module SIM Card Interface (VSIM, SIM_CLK, SIM_IO, SIM_RST): the SIM layout may be critical if the SIM card is placed far away from the LISA-U series modules or in close proximity to the RF antenna. In the first case the long connection can cause the radiation of some harmonics of the digital data frequency.

LISA-U series - System Integration Manual 2.2.3 Placement Optimize placement for minimum length of RF line and closer path from DC source for VCC. Make sure that RF and analog circuits are clearly separated from any other digital circuits on the system board. Provide enough clearance between the module and any external part due to solder and paste masks design.
LISA-U series - System Integration Manual 2.3 Thermal aspects The operating temperature range is specified in LISA-U1 series Data Sheet [1] and LISA-U2 series Data Sheet [2]. The most critical condition concerning thermal performance is the uplink transmission at maximum power (data upload or voice call in connected mode), when the baseband processor runs at full speed, radio circuits are all active and the RF power amplifier is driven to higher output RF power.
LISA-U series - System Integration Manual 2.4 Antenna guidelines Antenna characteristics are essential for good functionality of the module. Antenna radiating performance has direct impact on the reliability of connections over the Air Interface. A bad termination of the ANT pin (main RF input/output) and the ANT_DIV pin (RF input for diversity receiver provided by LISA-U230 modules) can result in poor performance of the module.
LISA-U series - System Integration Manual For integration observe these recommendations: Ensure 50 Ω antenna termination, minimize the V.S.W.R. or return loss, as this will optimize the electrical performance of the module. See section 2.4.1 Select antenna with best radiating performance. See section 2.4.2 If a cable is used to connect the antenna radiating element to application board, select a short cable with minimum insertion loss.
LISA-U series - System Integration Manual Figure 64 shows comparable measurements performed on a wideband antenna. The termination is better, but the size of the antenna is considerably larger. Figure 64: |S11| sample measurement of a wideband antenna 2.4.2 Antenna radiation An indication of the antenna’s radiated power can be approximated by measuring the |S21| from a target antenna to the measurement antenna, using a network analyzer with a wideband antenna.
LISA-U series - System Integration Manual Figure 66: |S11| and |S21| comparison between a 900 MHz tuned half wavelength dipole (green/purple) and a wideband commercial antenna (yellow/cyan) Instead if |S21| values for the tuned dipole are much better than the antenna under evaluation (like for marker 1/2 area of Figure 66, where dipole is 5 dB better), then it can be argued that the radiation of the target antenna (the wideband dipole in this case) is considerably less.

LISA-U series - System Integration Manual The Jamming Detection Feature detects such “artificial” interference and reports the start and stop of such conditions to the client, which can react appropriately by e.g. switching off the radio transceiver in order to reduce power consumption and monitoring the environment at constant periods.
LISA-U series - System Integration Manual Nevertheless there are environmental conditions that can affect operating temperature, e.g. if the device is located near a heating/cooling source, if there is/isn’t air circulating, etc. The module itself can also influence the environmental conditions; such as when it is transmitting at full power. In this case its temperature increases very quickly and can raise the temperature nearby.

Conversely, if performed excessively, fine balls and large balls will be generated in clusters. End Temperature: 150 - 200°C If the temperature is too low, non-melting tends to be caused in areas containing large heat capacity. Heating/ reflow phase The temperature rises above the liquidus temperature of 217°C.
LISA-U series - System Integration Manual 4.2.3 Optical inspection After soldering the LISA-U series modules, inspect the modules optically to verify that he module is properly aligned and centered. 4.2.4 Cleaning Cleaning the soldered modules is not recommended. Residues underneath the modules cannot be easily removed with a washing process. Cleaning with water will lead to capillary effects where water is absorbed in the gap between the baseboard and the module.
LISA-U series - System Integration Manual 4.2.10 Casting If casting is required, use viscose or another type of silicon pottant. The OEM is strongly advised to qualify such processes in combination with the LISA-U series modules before implementing this in the production.
