IF FILTER COMPENSATION
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. Figure 32 and Figure 33 show IF
filter compensation for NTSC and PAL, respectively.
The options for this feature are as follows:
•
•
•
See Table 107 for programming details.
Bypass mode
NTSC, consists of three filter characteristics
PAL, consists of three filter characteristics
