Function
Selection of input frequency range:
0:
1:
Maximum width of HSYNC (input SYNC):
0:
1:
Minimum width of HSYNC (input SYNC):
0:
1:
Nominal PLL output frequency: INC = 00110
For the allowed values of INC refer to table chapter 2.3.1!
Calculation of INC for low FH range:
for high FH range (2FH = 1):
Normal line frequencies (around 15.6 kHz)
Double line frequencies (31.2...38 kHz)
[YUV A/D converters are switched off]
6.2 s for low FH-range
3.1 s for high FH-range (2FH = 1)
9.0 s for low FH-range
4.5 s for high FH-range (2FH = 1)
3.0 s for low FH-range
1.5 s for high FH-range (2FH = 1)
1.7 s for low FH-range
0.8 s for high FH-range (2FH = 1)
