Single chip Hi-Fi audio signal

processor

BH7801BK

The BH7801BK incorporates the functions for a VHS audio signal processing system on a single chip. The circuits

on the chip are a peak-noise reduction processor (PNR), an FM modulator / demodulator circuit, an I / O switcher, an

automatic FM detector circuit, an FM bandpass filter, and a regulator circuit.

Applications

•

VCRs

Features

•

1) Operates off dual ± power supply which allows a

large reduction in the number of coupling capacitors

required. A built-in regulator makes it easy to con-

struct a power supply system.

5) The built-in bandpass filter excels at attenuation of

other channels, and can be directly coupled to the

playback amplifier. The FM recording output block

has a high-performance low-pass filter to produce

sine wave output.

2) A two-line I²C BUS control decoder circuit is provid-

ed, allowing the various IC modes to be set using

serial control.

6) Slope-control-type FM-switching-noise compensa-

tion circuit.

3) A four line input switcher is included (tuner, BS, and

line 1 / 2). The output switcher can switch between

STREO, LEFT, and RIGHT, and Hi-Fi, MIX, and

NORMAL, and a BS MONITOR function is also pro-

vided.

7) Envelope detector circuit and noise-detector-type

automatic FM detector circuit.

8) VCO that uses the color signal sub-carrier frequency

f^sc(NTSC: 3.579545MHz, PAL: 4.433619MHz) and

auto-adjusting BPF circuit ensure stable adjustment

with no fluctuation due to mounting stress or time.

4) The PNR processor and FM modulator / demodula-

tor circuit have reversed characteristics at recording

and playback. In addition, the adjustment for carrier

frequency and FM deviation / playback level are

common.
