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 Committee, 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 (t

MC44BC375U Features
