SM5843AP1規(guī)格書(shū)詳情
OVERVIEW
The SM5843A×1 is a multi-function digital filter IC, fabricated using NPC’s Molybdenum-gate CMOS process, for digital audio reproduction equipment. It features 8-times oversampling (interpolation), digital deemphasis and soft muting functions. It accepts 16, 18, or 20-bit input data, and outputs data in 18 or 20-bit format. It operates using either a 384fs or 256fs system clock.
FEATURES
■ Filter configuration (2-channel processing)
? 8-times oversampling (interpolation)
- 3-stage FIR configuration
? Deemphasis filter
- IIR filter configuration for correct gain and phase characteristics
- 2-channel independent ON/OFF control
- 32/44.1/48 kHz sampling frequency (fs)
? 21 × 22-bit parallel multiplier/25-bit accumulator for high precision
? Overflow limiter
■ 2 oversampling filter characteristics
? Sharp roll-off characteristic (response 1)
- ≤ ±0.00005 dB passband ripple (0 to 0.4535fs)
- ≥ 110 dB stopband attenuation (0.5465fs to 7.4535fs)
? Slow roll-off characteristic (response 2)
- ≤ ±0.00003 dB passband ripple (0 to 0.235fs)
- ≥ 77 dB stopband attenuation (0.745fs to 7.255fs)
■ Soft muting
■ Digital attenuator
■ Input data format
? 2s complement, MSB first
- LR alternating, 16/18/20-bit serial, trailing data
- LR alternating, 20-bit serial, leading data
- LR simultaneous, 20-bit serial, leading data
■ Output data format
? 2s complement, MSB first, LR simultaneous
? 18/20-bit serial
? BCKO burst (NPC format)
■ Dither processing ON/OFF control
■ Jitter-free/Sync mode selectable
■ 256fs/384fs system clock selectable
? 21.2/14.2MHz maximum frequency (384fs/256fs)
■ 5 V supply
■ Crystal oscillator circuit built-in
■ TTL-compatible input/outputs
■ 28-pin plastic DIP and SOP
■ Molybdenum-gate CMOS
APPLICATIONS
■ CD players
■ DAT players
■ PCM systems
