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 cir-  
cuits, and transversal filters (TVF).  
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.  
2) Built-in VCA, amplifier, buffer, and mixer amplifier.  
3) Detects the ATF pilot signal and generates an ATF  
error signal.
