Video ICs Equalizer and ATF circuit IC for Digital VCRs BH7273KV The BH7273KV is an equalizer and ATF circuit IC developed for use with digital video cassettes (DVC). By using this IC, it is simple to design the filter for the equalizer required for DVD sets. In addition, the ATF circuit detects the pilot signals and generates error signals. Applications • Equalizers and ATFs for digital VCRs Features • 1) Enables the configuring of all pass filters, 1 + D circuits, and transversal filters (TVF). 2) Built-in VCA, amplifier, buffer, and mixer amplifier. 3) Detects the ATF pilot signal and generates an ATF error signal. 4) Built-in 1.5MHz LPF, VCA, 465kHz BPF, 697.5kHz BPF, 25dB amplifier, peak detector, and subtractor.
