In MULTI-CHANNEL HIGH-PERFORMANCE MC-PA SERIES RF TRANSCEIVER ro TECHNOLOGIES WIRELESS MADE SIMPLE CPA SERIES TRANSCEIVER MODULE DESIGN GUIDE Description The P Aversion of Link's popular MC Series greatly reduces the time and expense of making a product wireless. This Is because the transceiver modules is per-approved by the FCC when used with the appropriate proprietary antennas. The TC-900-MC-PA transceiver module is designed for the high-performance bidirectional transfer of wireless data.
PERFORMANCE DATA TC-900-MC-PA ABOUT THESE MEASUREMENTS The performance parameters listed below are based on module operation at 25°C from a SVN supply unless otherwise noted.

PLL to the desired channel frequency. The micro-controller also monitors the swats of the PLL and indicates when the transmitter is stable and ready to transmit data by raising the Lock Detect (LD) fine high. The transceivers LD output is often used as a clear-to-send (CTS) indication so that data transmission can begin instantly upon PLL dock. Digital information is modulated at the transmitter using FSK {frequency shift keying), the binary form of frequency modulation.
POWER CONSIDERATIONS The transceiver has an on-board voltage regulator that regulates the internal VCC to A 3.0V. This allows a wide operating voltage range of 27V 10 16V. At 2.7V, the internal regulator Vee IN acts as a saturated switch, directly passing voltage through to the internal electronics. The 2 Tue PDN pin can be used to put the transceiver into a low-current sleep mode (<50uA}.
BOARD LAYOUT CONSIDERATIONS if you are at all familiar with BF devices, you may be concerned about specialized layout requirements. Fortunately, because of the care taken by Lin in the internal design of the module, integration 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. — 1.3" — 0.100" Typ.
events in a link incorporating MC series modules. There are many alternative methodologies but it is intended to Illustrate some of the considerations previously mentioned. The MC 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. When designing with a naif-duplex transceiver it is important to allow for the timing requirements when shifting between transmit and receive modes.
LEGAL CONSIDERATIONS The TC-300-MC-PA module has been previously tested and received certification as a modular product from the FCG. No further testing of the module is necessary when compliant antennas are employed. The per-certified status of the module is valid only if all of the flowing are observed: «No modifications to the module may be made. + The module must utilize Lin antennas which have been previously tested with the module and approved for FCC compliance.
