/Subject (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. 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 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 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. The MC44CC373CASEF has a secondary I2C address for applications using two modulators on one I2C Bus.)
