Texas Instruments TAS3308PZTR

Description
The TAS3308 is a fully programmable digital audio processor with analog interface. It is designed for use in a wide variety of audio applications, including flatscreen televisions, MP3 player/music phone docks, speaker bars, mini/microcomponent systems, automotive head units, and musical instruments.
The TAS3308 features a 135MHz operation, 48bit data path with 76bit accumulator, and hardware singlecycle multiplier (28 × 48). It also has five simultaneous operations per clock cycle, usable 1k data RAM words (48 bit), usable 1k coefficient RAM (28 bit), and usable 2.8k program RAM.
The TAS3308 also features a 360 ms at 48 kHz, 17k words 24bit delay memory, slave mode F, is 32.44.1 and 48 kHz with auto sample rate detection, and master mode F, is 48 kHz.
