M65818AFP

M65818AFP Digital Amplifier Processor of S-Master* Technology REJ03F0019-0100Z Rev.1.00 Sep.04.2003 Description The M65818AFP is a S-Master technique processor for digital amplifier enable to convert from multi liner-PCM digital input signal to high precise switching-pulse digital output without analog processing. The M65818AFP has built-in 24bit sampling rate converter and digital-gain-controller. The M65818AFP enables to realize high precise (X`tal oscillation precision) fully digital amplifier systems combining with power driver IC. Features Built-in 24bit Sampling Rate Converter. Input Signal Sampling Rate from 32KHz to 192KHz(24bit Maximum). 4 kinds of Digital Input Format. Built-in L/R Independent Digital Gain Control. Built-in Soft Mute Function with Exponential Approximate-Curve. Correspondence for SACD signal (64Fs 1bit,Fs=44.1KHz). Direct Output from Sampling Rate Converter. 3.3V and 5.0V Power Supply Operation at Output Clock, Input Data, and Control Signal Port Main Applications Master Clock Primary Clock: 256Fsi/512Fsi Secondary Clock: 1024Fso/512Fso Input Signal Format: MSB First Right Justified(16/20/24bit),MSB First Left Justified(24bit) LSB First Right Justified(24bit),I2S(24bit) Input Signal Sampling Rate from 32kHz to 192kHz. 8Fs Input Mode: Correspondence for External Digital Filter, Sampling Rate Converter Outputs.
