Overview
The LV1041M is a Dolby Prologic Surround signal-
processing IC that implements in a single chip the
functions of the Sanyo LV1016 and LA2786 ICs and
a master volume control for the center and surround
channels. This IC allows both systems of Dolby Prologic
surround and digital surround to be formed into a single
IC.
Features
Implements a Prologic surround decoder in a single
chip.
Wide dynamic range
All modes can be controlled from control data
transmitted serially over four lines: CLOCK, DATA,
ENABLE, and ENABLE2. This function is compatible
with the LV1016 and the LA2786.
Functions
Adaptive matrix
Center mode control (normal, phantom, wide)
4/3 channel logic control
Auto-balance (on/off)
Prologic off mode (bypass and full bypass)
Center trim (0 to –31 dB in 1-dB steps)
On-chip memory: (8K SRAM)
Variable delay time: 15, 20, 25, 30, 40, or 50 ms (15, 20,
25, or 30 ms for Dolby Prologic surround)
New A/D and D/A converter circuits adopted
On-chip Dolby B noise reduction
On-chip input and output filters
Built-in VDD circuit
Surround trim (0 to –31 dB in 1-dB steps)
Input and output muting functions
Master volume control for the center and surround
channels (0 to –44 dB in –2-dB steps, –44 to –76 dB in
