SL5162

Multistandard VHF and UHF Television Demodulator

Supersedes September 1996 edition, DS4497-2.1

DS4497-3.0 September 1998

The SL5162 multistandard modulator up-converts a

baseband video signal with separate audio frequency input

on to a VHF or UHF carrier up to 860MHz. It provides RF

signals with negative or positive video modulation and AM

or FM sound subcarrier to satisfy both PAL/NTSC and

SECAM applications.

The on-chip local oscillator uses an external resonator

tank which may be controlled via any Mitel 1.3GHz

synthesiser. Selection of both video and sound standards

are provided by level switching of a single pin.

A video AGC circuit is provided to ensure constant

modulation depth. In PAL mode this may be disabled and

a white clip circuit switched in to prevent overmodulation if

desired.
