4 Receiver Configuration

CTLEMAP_SEL: The TDP1204 in pin-strap mode has three CTLE HDMI Datarate Maps: Map A, Map B, and Map C. Map A and C should be used if TDP1204 is used in a source application and Map B for a sink application.

Receiver equalization: The receiver equalizer is used to clean up inter-symbol interference (ISI) jitter. TDP1204 supports fixed receiver equalizer by setting the EQ0 and EQ1 pins in pin-strap mode or through I2C register. TDP1204 also supports adaptive equalization (AEQ) for HDMI2.1 FRL as determined by the MODE pin configuration. The adaptive equalization starts when FRL link training begins. It will also re-adapt each time the datarate changes. The adaption will only occur during the TXFFE0 portion of FRL link training when LTP5, LTP6, LTP7, or LTP8 is being received.
