• Manufacturer Part Number: tda5235
• Description: Enhanced Sensitivity Double-configuration Receiver With Digital Baseband Processing
• Manufacturer: Infineon Technologies Corporation

In addition, it has to be considered that some data bits are required for synchronization
and internal latency (see
Inter-Frame
Calculation of the Off time:
The same general rules apply as for Constant On-Off Time. The Off time has to be short
enough that no wake-up pattern reception is missed.

This mode combines Constant-On Time and Fast Fall Back to SLEEP within different
configuration sets: Cfg.A: COO; Cfg.B: FFB

In Mixed Mode the On time of Configuration B is used for the FFB group. Below there
are shown the same scenarios as before, but now for Mixed Mode. Note that Single-
Configuration can be set, but is not recommended in Mixed Mode.
