SANYO LV1100 Datasheet

Overview

The LV1100 is an audio signal-processing Bi-CMOS LSI
that integrates input and output filters, a delay line (built­in memory), and a delay/reverb function with a maximum
delay of 120 ms on a single chip. It also provides built-in
fixed matrix (L+R, L–R) and front mixing (with level and
phase switching) functions. A full complement of
surround modes can be easily implemented by combining
these functions.

Functions and Features

• Input switching (L+R, L–R, IN–A)

• On-chip memory (12K SRAM)

• Front adder (+3 dB, 0 dB, –3 dB, -∞)

• Input and output filters

• Input filter –7 kHz low-pass filter

• Output filter –5 kHz low-pass filter: switchable with a
3 kHz low-pass filter

• On-chip VDDcircuit

• Input and output muting function

• A simulated surround system can be easily implemented
with only one chip.

• ADM A/D and D/A converters

• Variable delay times
– Short mode; Maximum delay: 60 ms. Delay time

selectable from six delay times in 10-ms steps.

– Long mode; Maximum delay: 120 ms. Delay time

selectable from six delay times in 20-ms steps.

Test Circuit

Notes: 1. The items D1 through D10 in the figure indicate points that are switched by the serial data.

2. Use capacitors with good high-frequency characteristics for the capacitors on pins 7, 14, and 22. Also, connect 0.1-µF ceramic capacitors in
parallel.

Note: The items D1 through D10 in the figure indicate points that are switched by the serial data.
