LV1100 Digital Surround Audio Signal-Processing IC

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. 3.INPUT FILTER Selects whether .

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 the.
