 CMOS Audio/Video RF Modulators

The AS44CE373 / AS44CE374 CMOS family of RF modulators is the latest
generation of the legacy MC44BS373/4 family of devices. They are pin-to-pin
compatible and functionally equivalent to the previous family of the AS44CC373/
374.
The AS44CE373/AS44CE374 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 I2C Bus.
A programmable, internal PLL, with on-chip LC 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 low cost 4 or 16 MHz crystal, or from an
external frequency reference at these frequencies.
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.
They are however fully compatible with the AS44CC373/4 series.
All devices now include the AUXIN found previously only on the 20-pin package
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.
