FSC
Bits Field Name Description Type Reset
31:0 FSC These four bytes' data program the color subcarrier frequency and are RW 0x21F07C1F
determined by the following formula.
S_CARR = ROUND((Fsc/Fclkenc) * 2
32
)
Where: Fsc = Frequency of the subcarrier
Fclkenc = Frequency of the internal video encoding clock = 2*LLEN *Fh
LLEN = Number of pixels in a scan line. For LLEN setting, please refer
to the description of
VENC_LLEN register (offset 0x1C).
Fh = Line frequency
For typical setting of the FSC field, refer to
Table 7-40 .
