Ordering number : EN6094

N2598RM (OT) No. 6094-1/22

Overview

The LV1110NM is a digital surround processor IC
developed for miniature stereo components and radio­cassette 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
