IF Compensation Filter
IFFILTSEL[2:0] IF Filter Select Address 0xF8[2:0]
The IFFILTSEL[2:0] register allows the user to compensate for
SAW filter characteristics on a composite input as would be
observed on tuner outputs.
245HFigure 36 and 246HFigure 37 show IF
filter compensation for NTSC and PAL.
The options for this feature are as follows:
•
Bypass Mode (default)
•
NTSC—consists of three filter characteristics
•
PAL—consists of three filter characteristics
