Overview
The LV1100 is an audio signal-processing Bi-CMOS LSI
that integrates input and output filters, a delay line (built-
in 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.
Functions and 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 only one chip.
ADM A/D and D/A converters
