Audio/Video RF CMOS Modulators

MC44CM373/4

The MC44CM373/MC44CM374 CMOS family

of RF modulators is the latest generation of

the legacy MC44BS373/4 family of devices.

The MC44CM373/4 RF modulators are

designed for use in VCRs, set-top boxes

and similar devices. They support multiple

standards and can be programmed to support

PAL, SECAM or NTSC formats.

The devices are programmed by a

high-speed I

family is backward compatible with the

previous I

smooth transition for system upgrades.

A programmable, internal Phase-Lock Loop

(PLL), with an on-chip, cost-effective tank

covers the full UHF range. The modulators

incorporate a programmable, on-chip,

sound subcarrier oscillator that covers all

broadcast standards. No external tank

circuit components are required, reducing

PCB complexity and the need for external

adjustments. The PLL obtains its reference

from a cost-effective 4 MHz crystal oscillator.

The devices are available in a 16-pin SOIC,

Pb-free package. These parts are functionally

equivalent to the MC44BS373/4 series, but

are not direct drop-in replacements.

All devices now include the aux input found

previously only on the 20-pin package

option. This is a direct input for a modulated

subcarrier and is useful in BTSC or NICAM

stereo sound or other subcarrier applications.

The MC44CM373CASEF has a secondary I

address for applications using two modulators

on one I

C Bus.

C control software, providing a

C bus. The MC44CM373/374

Typical Applications

The MC44CM373 and MC44CM374 RF

modulators are intended for applications

within IP/DSL, digital terrestrial, satellite

or cable set-top boxes, VCRs and DVD

players or recorders, game consoles or

audio/video redistribution.
