• Manufacturer Part Number: tda5225
• Description: Enhanced Sensitivity Multi-channel Quad-conf Igurat Ion Receiver With Digital Slicer
• Manufacturer: Infineon Technologies Corporation

Configuration A can follow or the TDA5225 can proceed receiving another (redundant)
payload data frame within the same configuration.
The transparent data stream has to be processed externally by the Application
Controller. Therefore the external controller needs the possibility to send following
commands (see
•
•
When the actual processed configuration is right before the Off time and the Application
Controller sends one of the above mentioned commands, then the TDA5225 can
proceed with the Off time (in case next configuration is selected).
In Constant On-Off Time Mode the Polling Timer is always initialized after a TOTIM or
EOM event. This means a new On period is always started.
Data Sheet
EXTTOTIM: So the TDA5225 can proceed with Self Polling Mode (either with the
next programmed channel or with Configuration A).
EXTEOM found: In this case the TDA5225 can either proceed with Self Polling Mode
(either with the next configuration or with Configuration A) or stay in Run Mode Self
Polling.
