LV1100 - Digital Surround Audio Signal-Processing IC

General Description

1.INPUT PHASE SELECT Selects either the input summation signal (L+R) or the input difference signal (L-R).

When set to low, L+R is selected, and when set to high, L-R is selected.

2.INPUT SELECT Selects either the IN-L and IN-R input signals, or the IN-A input signal.

Key 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 VDD circuit Input and output muting function A simulated surround system can be easily implemented with onl.

Ordering number : EN5506 Bi-CMOS LSI LV1100 Digital Surround Audio Signal-Processing IC 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.
