Overview
The LV1110NM is a digital surround processor IC
developed for miniature stereo components and radio-
cassette combinations. The major features built into this
Bi-CMOS single-chip solution are function switching,
recording volume control, surround processing, karaoke
processing, 3-band graphic equalizer, and master volume
control.
Features
The built-in delay functions include input and output
filters, analog-to-digital and digital-to-analog converters,
delay lines with built-in memory, and delay
reverberation. Other functions available are fixed matrix
(L+R and L-R) and front mixing (choice of level or
phase). These functions may be freely combined to
easily produce a variety of surround modes and thus
simulate a wide range of acoustic environments.
The built-in karaoke functions include a vocal canceler,
microphone echo, key control I/O, and other support for
audio multiplexing software.
Functions
Input function switching (Five channels with built-in
6-dB amplifier)
Two REC output pins with volume controls (Two
channels with on/off switches and choice of function
output or mixer output)
Input switching (choice of L+R, L–R, and L or R only)
Microphone input (on/off)
Vocal canceler
Key control I/O pins
Front addition (+3 dB, –3 dB, –5 dB, mute)
I/O filters in delay block (choice of 2-, 5-, and 28-kHz
low pass filters or through operation)
Reverberation functions (with built-in volume control)
Built-in SRAM (8 kilobytes)
Variable delay (choice of 15, 20, 25, 30, 40, 50, 100,
and 120 ms)
Built-in V
DD
I/O through or mute
Three-band graphic equalizer (boost or cut with three
steps each)
Master volume control from 0 to –79 dB in 1-dB steps
QIP-64E package with 0.8-mm pin pitch
