I HIGH-PERFORMANCE PER-CERTIFIED TECHNOLOGIES RF TRANSCEIVER SC SERIES TRANSCEIVER MODULE DESIGN GUIDE DRAFT FOR FCC SUBMISSION DO NOT DISTRIBUTE UNTIL APPROVAL IS GRANTED AND DOCUMENT CONTROL HAS RELEASED! DESCRIPTION: The TC-XXX-8-P{ transceiver module is designed for the cost-effective, bi-directional transfer of wireless information. The transceiver is completely self-contained and requires no external RF components. The PQ version of the SC has 1.
PERFORMANCE DATA TC-XXX-SC ABOUT THESE MEASUREMENTS The performance parameters listed below are based on module operation at 25°C from a BY DC supply unless otherwise noted.

TRANSMITTER OPERATION The transmitter is a wide-band FM transmitter capable of generating 1mW of output power into a 50-chm load, The transmitter is comprised of a LO and crystal-controlled frequency synthesizer. The frequency synthesizer phase Jocks the LO to a precision crystal to achieve a high-Q, low phase-noise oscillator. FM modulation is achieved by varying a reactance in series with the reference crystal. By modulating the transmitter in this manner, a wide modulation bandwidth is achieved.
BOARD LAYOUT CONSIDERATIONS If you are at all familiar with RF devices, you may be concerned about specialized layout requirements. Fortunately, because of the care taken by Lin in the layout of the module's PCB, integrating an TC-XXX-SC receiver into your design is very straightforward. By adhering carefully to a few basic design and layout rules, you can enjoy a trouble-free path to RF success. Figure 8 shows the suggested PCB footprint for the SC Series transceiver.
The SC series is a half-duplex transceiver. This means that the transceiver itself can only act as a transmitter or a receiver at any given time, but never both Designing a system with a haft-duplex transceiver is a lite more challenging because of the timing requirements when shifting between transmit and receive modes. In a typical system, the operation will be as follows: 1) Switch to transmit mode The transceiver is placed in transmit mode by bringing TEN high and OXEN jow.
LEGAL CONSIDERATIONS The TR-916-SC module has been previously tested and received further certification as a modular product. The per-certified status of the module is valid only if all of the following are observed: «No modifications to the module may be made. + The module must utilize Lin RH or CW series antennas. These antennas utilize non-standard connectors and were the antennas utilized for device approval. «The per-certified status applies only to the RF module.
