The LSI has built-in A/D,D/A converters which enable digital sound processing for analog signals. With a 256k pseudo SRAM orSRAM connected, the LSI can process digital delay up to 512ms.FEATURES- Built-in 15-bit floating ADC (L, R 2 channels) and DAC (FL, FR, RL, RR4 channels) enable digitalprocessing for analog signals with 32kHz internal sampling frequency.- 4 channels except center output can output digital signals as well. With a DAC connected externally, it willbe possible with up to 5 channels (FL, C, FR, RL, RR).- Hi-performance surround by mixing many echoes with using up to 512ms digital delay.- Preset mode for easy control by terminal setting.- Register control mode where it is possible to set various coefficients using microprocessor serialinterface for original sound processing.- Internal DSP is a 24-bit x 13-bit high speed multiplier with 128 steps.- One 256k (32k x 8) pseudo SRAM or SRAM to be connected.- 12.288MHz (384fs) master clock.- 5V single power supply, Si-gate CMOS process.- 64-pin plastic QFP (YSS220-F)Note: Due to the nature of the product, the preset data cannot be disclosed although partially.PIN DESCRIPTION54No.NameI/OPin Function Description1MD4I/OExternal RAM interface data
