SM5841HS规格书详情

OVERVIEW

The SM5841H is an 8-times oversampling (interpolation) digital filter for digital audio reproduction equipment. It accepts 16 or 18-bit input data, and outputs data in 16, 18 or 20-bit format, making a wide range of interfaces possible. It also features digital deemphasis for 3 sampling frequencies, a noise shaper to reduce quantization noise, a DC off=set output and other circuits

FEATURES

Functions

■ 2-channel processing

■ 8-times (8fs) oversampling (interpolation)

■ Digital deemphasis (fs = 48/44.1/32 kHz)

■ Serial input data

2s complement, MSB first, 16/18-bit

■ Serial output data

2s complement, MSB first, 16/18/20-bit

■ 1st-order noise shaper (for 16/18-bit output only)

■ 256fs/384fs system clock selectable

■ Output data DC offset (approximately 0.8)

ON/OFF control

■ TTL-compatible input/outputs

■ 5 V (standard) supply

■ 3.2 V operating voltage

■ Molybdenum-gate CMOS

Filter Characteristics

■ 3-stage DC FIR interpolation filter

1st stage (fs → 2fs), 69-tap

2nd stage (2fs → 4fs), 13-tap

3rd stage (4fs → 8fs), 9-tap

■ IIR deemphasis filter for gain and phase

characteristics close to those of analog filters

■ Overflow limiter built-in

APPLICATIONS

■ Digital amplifiers
