Philips Semiconductors
Product specification
General Digital Input (GDIN)
TDA1373H
FEATURES
Four operating modes:
– Sample Rate Conversion (SRC) mode
– AD/DA mode
– SLAVE-VCO mode
– SLAVE-VCXO mode
Full digital sample rate conversion over a wide range of
input sample rates
Fast and automatic detection and locking to the input
sample rate with continuous tracking
Digital Phase-Locked Loop (PLL) with adaptive
bandwidth which removes jitter on the digital audio input
Audio outputs (soft) muted during loop acquisition
Full linear phase processing based on all-FIR filtering
Integrated full digital IEC 958 demodulator for digital
input signals (AES/EBU or SPDIF format) with intelligent
error handling
Extended input sample frequency range
IEC 958 Channel Status (CS) and User Channel (UC)
outputs
On-chip CS and/or UC demodulation and buffering
(consumer and professional format)
Dedicated subcode processing for Compact Disc (CD)
Final output quantization to 16, 18 or 20 bits with
optional in-audio-band noise shaping
Bitstream input and output for coupling with 1-bit
analog-to-digital conversion (ADC) and digital-to-analog
conversion (DAC)
