AGC Saturation Limit (Points/Lines)
The SATLMTPT[1:0] and SATLMTLN[1:0] bits are used to program the CVBS Saturation Threshold. It is
expressed as a number of samples per field (when, according to the algorithm, the number of samples is
reached, the gain is decreased). The formula for the threshold computation is the following:
AGC SMHI Threshold Value
This bitfield defines the Luma Low Signal Detection Threshold (when, according to the algorithm, the luma
signal remains under that threshold, the gain is increased). The threshold is defined as an ADC (10 bit)
code output according to the following formula:
AGC ACTI Threshold Value
This bitfield defines the Luma Saturation Threshold (when, according to the algorithm, the luma signal
overtakes that threshold, the gain is decreased). The threshold is defined as an ADC (10 bit) code output
according to the following formula:
Reserved. Must be set to 1. Recommended value: 1 (instead of 0 at reset).
Reserved. Must be set to 1.
Standard ID Enable
This bit modifies the standard identification algorithm. When this bit is set (default), the standard
identification algorithm disregards the auto identification table entries not corresponding to the 50 or 60Hz
detection performed by the synchronization block.
Threshold = 1 + 4 x SATLMTPT[1:0] +16 x SATLMTLN[1:0]
Threshold = 772 + 8 x SMHITH[1:0] (Default = 772 + 8 x 2)
Threshold = 807 + 8 x ACTITH[1:0] (Default = 807 + 8 x 2)
