The SMT application interface incorporates the various application interfaces as well as the RF antenna interface. 2.1 Application Interface 2.1.1 USB Interface EHS8 supports a USB 2.0 High Speed (480Mbit/s) device interface that is Full Speed (12Mbit/s) compliant.
Cinterion® EHS8 Hardware Interface Overview Page 15 of 43 2.1 Application Interface 24 2.1.2 Serial Interface ASC0 EHS8 offers an 8-wire unbalanced, asynchronous modem interface ASC0 conforming to ITUT V.24 protocol DCE signalling. The electrical characteristics do not comply with ITU-T V.28. The significant levels are 0V (for low data bit or active state) and 1.8V (for high data bit or inactive state). EHS8 is designed for use as a DCE.

The trace length of these signals should be balanced to minimize timing skew and no longer as 100mm. Four signal lines for Link Power Management (LPM). For further power reduction, the USB HSIC interface supports LPM according to the USB 2.0 standard.
Cinterion® EHS8 Hardware Interface Overview Page 21 of 43 2.2 RF Antenna Interface 24 2.2 RF Antenna Interface The RF interface has an impedance of 50 . EHS8 is capable of sustaining a total mismatch at the antenna line without any damage, even when transmitting at maximum RF power. The external antenna must be matched properly to achieve best performance regarding radiated power, modulation accuracy and harmonic suppression.
Cinterion® EHS8 Hardware Interface Overview Page 22 of 43 2.2 RF Antenna Interface 24 2.2.1 Antenna Installation The antenna is connected by soldering the antenna pad (ANT_GSM, i.e., pad #59) and its neighboring ground pads (GND, i.e., pads #58 and #60) directly to the application’s PCB. The antenna pad is the antenna reference point (ARP) for EHS8. All RF data specified throughout this document is related to the ARP.
Cinterion® EHS8 Hardware Interface Overview Page 23 of 43 2.3 GPS Interface 24 2.3 GPS Interface 2.3.1 GPS Receiver EHS8 integrates a GPS receiver that offers the full performance of GPS technology. The GPS receiver is able to continuously track all satellites in view, thus providing accurate satellite position data. The integrated GPS receiver supports the NMEA protocol via ASC0 interface.
Cinterion® EHS8 Hardware Interface Overview Page 24 of 43 potential interferers may be minimized by placing small capacitors (47pF) at suspected lines (e.g. RXD0, RXT0, VDDLP, and ON). While developing SMT applications it is strongly recommended to provide test points for certain signals, i.e., lines to and from the module - for debug and/or test purposes. The SMT application should allow for an easy access to these signals. For details on how to implement test points see [3].

Cinterion® EHS8 Hardware Interface Overview Page 27 of 43 Please note that throughout the document BATT+ refers to both voltage domains and power supply lines - BATT+BB and BATT+RF. The power supply of EHS8 has to be a single voltage source at BATT+BB and BATT+RF. It must be able to provide the peak current during the uplink transmission. All the key functions for supplying power to the device are handled by the power management section of the analog controller.
