MC44BC375U Datasheet | Freescale Semiconductor

Freescale Semiconductor Data Sheet Document Number: MC44BC375U Rev 3, 8/2006 PLL Tuned VHF (Channel 3 / 4) Audio / Video Modulator The MC44BC375U and MC44BC375UA are audio/video RF modulators for use in VCRs, set-top boxes, and similar devices. They are designed for applications requiring National Television System mittee, NTSC, channel 3 or channel 4, RF outputs. The difference between the two modulators is the RF output power level. The nominal RFOUT level for the MC44BC375U is 76 dBµV (typical) and the RFOUT level for the MC44BC375UA is 80 dBµV (typical). A programmable Phase-Locked Loop (PLL) tunes the modulator, and the desired channel 3 or 4 frequency isselected using the...
