SAA7199B
Note
1.
Field blanking (Figs 11 and 12): normally, video to be encoded should not become active after the active edge of
VSN or CSYN before line 22.5 at 50 Hz (line 18 at 60 Hz). Total internal field blanking is 11 lines at 50 Hz (13 lines
at 60 Hz).

polarity of external PAL-ID signal (H/2 signal) from RTCI input (pin 57): 0 = not inverted;
1 = inverted
Real time select control: 0 = real time control HPLL increment is selected, which means,
information concerning actual clock frequency from the digital colour decoder is received
(SAA7151B or SAA7191B); the corresponding subcarrier frequency is calculated; 1 = real time
control FSC increment with PAL-ID is selected, which means, information concerning actual
subcarrier frequency and PAL-ID from the digital colour decoder is received (SAA7151B or
SAA7191B).
select real time control input: 0 = pin 57 is input for RTCI signal; 1 = pin 57 is port output GPSW
real time control enabled: 0 = disabled; 1 = enabled (RTIN = 0)
phase adjustment between chrominance output signal and reference: 00 to FF equals
0 to 358.59375 degrees in steps of 1.40625 degrees
fine adjustment of subcarrier frequency in non-GENLOCK modes: 00 to 7F increasing and
FF to 80 decreasing equal approximately to 450
