SM5846AP规格书详情
OVERVIEW
The SM5846AP is a multi-function digital filter that incorporates 4/8 times oversampling digital audio signal reproduction, digital deemphasis, digital attenuation and soft mute functions. The I/O interface allows serial data transmission of 16/20/24/32-bit input data and 20/24-bit output data.
FEATURES
Functions
■ 8-times oversampling (interpolation)
■ Switchable 8/4 times oversampling output
■ Two master clock frequencies (refer to Clock Functions)
• 384fs/512fs (normal-speed sampling)
• 192fs/256fs (high-speed sampling)
■ Digital deemphasis
• Compatible with 32/44.1/48kHz (normal speed) and 64/88.2/96kHz (high-speed) input sampling frequencies
• ON/OFF control
■ Digital attenuator
• 128-step attenuation using linear 7-bit data setting
■ Soft muting
• 1016/fs (normal-speed sampling)
• 2032/fs (high-speed sampling)
■ Output data round-off operation (normal round-off or rectangular distribution dither round-off)
■ Selectable LR clock polarity
■ Microprocessor controllable
■ Input data format
• 2s complement, MSB first, alternating L/R serial
• 16/20/24/32-bit data selectable
