Document Number: MC44BC375U  
Rev 3, 8/2006  
Freescale Semiconductor  
Data Sheet  
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 applica-  
tions requiring National Television System Committee, NTSC, channel 3 or chan-  
nel 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).  
MC44BC375U  
MC44BC375UA  
PLL TUNED VHF  
(CHANNEL 3 / 4)  
AUDIO / VIDEO MODULATOR  
A programmable Phase-Locked Loop (PLL) tunes the modulator, and the de-  
sired channel 3 or 4 frequency isselected using the external package pin, Chan-  
nel Selection (CHS). No external tank circuit components are required, reducing  
the sensitivity of the PCB design and the need for external adjustments. The PLL  
obtains its reference from a 4.0 MHz crystal oscillator.  
The modulators incorporate a sound subcarrier oscillator and use a second  
programmable PLL to derive subcarrier frequencies. The 4.5 MHz or 5.5 MHz  
sound carrier frequency is selectable via the package pin, Sound Frequency Se-  
lection (SFS). The Picture to Sound subcarrier ratio is also selectable by the pin,  
Picture to Sound Selection (PSS), to choose either a 14 dB or 16 dB ratio.  
A low-power standby mode is selectable via the pin, Psave/LO, which turns off  
all internal VCOs and mixers and simultaneously switches ON an output pin,  
Logic Output Port (LOP), which may be used as an antenna switch driver.
