CMOS Audio/Video RF Modulators
generation of the legacy MC44BS373/4 family of devices.
set-top boxes, and similar devices.They support multiple standards, and can be
programmed to support PAL, SECAM, or NTSC formats.
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.
