SECAM chroma signal processor for
VHS VCRs
BA7207AS / BA7207AK
The BA7207AS and BA7207AK are LSI components that incorporate the contain circuitry required for SECAM chro-
ma signal processing. The ICs have both recording and playback systems and each includes a bell filter, a band-
pass filter, a limiter amplifier, a multiply-by-four circuit, a divide-by-four circuit, and a sync-gate circuit.
Applications
SECAM and VHS format video cassette recorders and
camcorders
Features
1) All filters required for SECAM chroma signal pro-
cessing are provided.
2) Built-in chroma killer circuit.
3) Built-in switch circuit for selecting PAL chroma or
SECAM chroma for the PB / REC system output.
