LV1110NM

Ordering number : EN6094 Bi-CMOS IC LV1110NM 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 0.8-mm pin pitch Package ...
