PLL-SPLIT VIF/SIF IC

An output amplitude is positive 2.2VP-P in the case of 87.5%

video modulation.

1.4VO-P

In the locked state, the cut-off frequency of the filter is

adjusted effectively by an external resistor so that it will be

in the range of around 30 to 200kHz.

In case the cut-off frequency is lower, the pull-in speed

becomes slow. On the other hand, a higher cut-off frequency

widen the pull-in range and band width, which results

in a degradation in the S/N ratio. So, in the actual TV system

design, the appropriate constant should be chosen for getting

desirable performance considering above conditions.

It is an open-base input.

The IF AGC does not work correctly, unless a DC element

of pin 8 output is applied to it.
