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 cir-
cuits, 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.
5) Intermediate frequencies are variable by controlling
the voltages for the 465kHz BPF and 697.5kHz
BPF.
