3.5.7. TX Data Rate Generator
The data rate is configurable between 0.123256 kbps. For data rates below 30 kbps the txdtrtscale bit in register
70h should be set to 1. When higher data rates are used this bit should be set to 0.
The TX date rate is determined by the following formula in bps:
For data rates higher than 100 kbps, Register 58h should be changed from its default of 80h to C0h. Non-optimal
modulation and increased eye closure will result if this setting is not made for data rates higher than 100 kbps. The
txdr register is only applicable to TX mode and does not need to be programmed for RX mode. The RX bandwidth
which is partly determined from the data rate is programmed separately.
