M65818AFP Datasheet | Renesas

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 bining 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 32k Hz to 192k Hz. - 8Fs Input Mode: Correspondence for External Digital Filter, Sampling Rate Converter Outputs. - Gain Control Function: +30d B~ -∞d B(0.1d B Step until -96d B, -138d B Minimum) - Third Order ∆Σ (16Fso:6bit/5bit,32Fso: 5bit) - Sampling Rate Converter Output :MSB First Left justified /Lch,Rch Independent/32BCK Remended Operating Conditions Logic Block:3.3V±10%, PWM Buffer Block : 5.0V±10% (- - "S-Master" is the digital amplifier technology developed by Sony Corporation.
