Digital Surround Processor IC
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.
• 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 VDD • 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.
