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

In default mode the CH_STR signal is active high and has a delay of T
the data chip and a duration of T
programmable, this can be done via PPCFG2 register.

Transparent Mode - Matched Filter (TMMF)
The received data after the Matched Filter (Two-Chip Matched Filter) with an additional
SIGN function is provided via the DATA_MATCHFIL signal (PPx pin). In this mode
sensitivity measurements with ideal data clock can be performed very simple. For further
details see the block diagram in
Sensitivity in this transparent mode is significantly depending on the implemented clock
and data recovery algorithm of the user software in the application controller.

Transparent Mode - Raw Data Slicer (TMRDS)
This mode supports processing of data even without bi-phase encoding (e.g. NRZ
coding) by providing the received data via the One-Chip Matched Filter on the DATA
signal (PPx pin). See more details in the block diagram in
