TDA8754
Triple 8-bit video ADC up to 270 Msample/s
9.15 Inverter register
4
CLPSEL1
can be used to select the clamp signal; see bit CLPSEL2
0 = PLL reference signal
1 = clamp input
3
CLPH
inhibits the clamp signal during the Vsynco or coast signal; see bit TSTCOAST (Table 46)
0 = clamp inhibited during Vsynco
1 = clamp active during Vsynco
2
CLPENL
denes if clamp input works on edge or on level
0 = on edge; for all frequencies (must be preferably chosen)
1 = on level; only for frequencies below 45 MHz to have proper clamp function
1
ICLP
dedicated for test mode; should be forced to logic 0
0
CLPT
denes if the test mode of the clamp is active
0 = not active
1 = active
