1. RxC is RTxC or TRxC, whichever is supplying the receive clock.
2. TxC is TRxC or RTxC, whichever is supplying the transmit clock.
3. Both RTxC and SYNC have 30 pf capacitors to ground connected to them.
4. Synchronization of RxC to PCLK is eliminated in divide by four operation.
5. Parameter applies only to FM encoding/decoding.
6. Parameter applies only for transmitter and receiver; DPLL and BRG timing requirements are identical to PCLK
7. The maximum transmit or receive data rate is 1/4 PCLK.
8. Applies to the DPLL clock source only. Maximum data rate of 1/4 PCLK still applies. DPLL clock must have a
