CMOS Audio/Video RF Modulators

The MC44CC373 / MC44CC374 CMOS family of RF modulators is the latest

generation of the legacy MC44BS373/4 family of devices.

The MC44CC373/MC44CC374 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.

A programmable, internal PLL, with on-chip LC tank covers the full UHF range.

The modulators incorporate a programmable, on-chip, sound subcarrier oscil-

lator 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 low cost 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 re-

placements.

age option of the MC44BS373. This is a direct input for a modulated subcarrier

and is useful in BTSC or NICAM stereo sound or other subcarrier applications.
