Based on the recommended value of 3.5 bits for the RUNIN, the recommended setting
for SYSRTC0 = 0x87. This value is automatically used by the IAF TDA523x
Configuration Tool!

1) the value should be set in T/16 steps
A Second important system parameter which must be considered, is the minimal Inter-
Frame Time (time in between two data frames). This time is equal to the T
a length of 2 bits. The EOM to PLL re-synchronization time is negligible (this time is T/16
bit), and the system delay T
synchronization only.
Note that the described Inter-Frame Time is based on the input pattern with equal signal
power in the following telegram, in other cases the Inter-Frame Time can vary from the
calculated value.
2.4.9.2
The Digital Receiver processes input signals from the digital FSK Demodulator as well
as from the A/D-converted output signal of the RSSI generator used for ASK modulated
data signals. Input selection of the Digital Receiver is done by a multiplexer, which is
controlled by the Master Control Unit via the control signal Modulation Type. An optional
Pre-Slicer Unit may be activated in certain ASK applications to further increase the
jammer performance of the receiver.
