This LSI is the digital sound processor which made the use digital signal processing for FPD TVs.

DSP of ROHM original is used for the TV sound processor unit, and it excels in cost performance.

There are two digital input systems.

Digital Signal Processor unit Word length: The fastest machine cycle: Multiplier: Adder: Data RAM: Coefficient RAM: Sampling frequency: Master clock : No.12083EAT04 32bit (Data RAM) 40.7ns (512fs, fs = 48kHz) 32 x 24 → 56bit 32 + 32 → 32bit 256 x 32bit 128 x 24bit fs = 48kHz 512fs (It is a slave to 256fs of fs = 48kHz, 44.1 kHz, and 32 kHz).
