DPL 3519A DOLBY SURROUND PROLOGIC IC.
The DPL 3519A processor is designed to decode Dolby encoded surround sound. The IC integrates the complete
Dolby Surround Pro Logic decoding on chip without any necessary external circuitry. The DPL 3519A is designed as
a coprocessor to the MSP family. Together with the MSP, a TV set with up to six outputs (L,R,C,SUB,SL,SR) can be
developed together with headphones and several line outputs.
