Features
* Two RF output power levels offered:
* MC44BC375U has typical RFOUT power of 76 dBµV
* MC44BC375UA has typical RFOUT power of 80 dBµV U. S. broadcast frequency for Channel 3 or 4 operation is selected by CHS pin Programmable VHF oscillator and sound subcarrier oscillator. No
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 (typical) and the RFOUT level for the MC44BC375UA is 80 dBµV (typical). A programmab
