There are two RX settings possible. For a data rate of 1152 kBits/s, an internal clock recovery
function is implemented.
Must be used for data rates below 1.152 Mbits/s.
Recommended for 1.152-Mbit/s data rate.
The output pin of the recovered clock is pin 6. The falling edge of the recovered clock signal
samples the data signal.
RC, MC and SC bits control the synthesizer frequency as shown in
12
Formula for calculating the frequency:
TX frequency: f
RX frequency: f
