Table 1 Pin descriptions

VIDEO INPUT SECTION

A composite signal of the selected standard is applied to

the device via a coupling capacitor also acting as the clamp

storage capacitor. A minimum level clamp is used to DC

restore the video signal in the IC to an internally defined

reference voltage.

The AGC will give a constant output level with input signals

between 0·5 and 1·5 Vp-p. If a controlled 1Vp-p video signal

is available, the AGC may be disabled, in which case a white

clip circuit is switched in, to prevent possible overmodulation.

Selection of negative or positive modulation is via a single

pin (14). The voltage on this pin controls an offset which is fed

to the UHF mixer, thus determining both modulation depth,

and sense of modulation.

SOUND SECTION

The sound is AC coupled and AM or FM modulated onto

the pre-selected carrier, 4·5 - 6·5MHz; its level is nominally at

16dB relative to the peak vision carrier.

UHF MODULATED OUTPUT

Modulation and relative levels of vision and sound carrier

levels are preset for the selected broadcast standard.

Table 2 gives the output options available. Modulation index

is fixed at 83% for all negative modulation systems and at 94%

for SECAM standard L. Selection of sound tank frequency is

defined by off-chip tank components.
