TDA1373H is a general digital input (GDIN) integrated circuit from Philips Semiconductors. It has four operating modes: sample rate conversion (SRC) mode, AD/DA mode, SLAVE-VCO mode and SLAVE-VCXO mode. It supports a wide range of input sample rates and has fast and automatic detection and locking to the input sample rate with continuous tracking.
The TDA1373H is an integrated circuit designed for professional audio equipment, including CD-Recordable drives, digital amplifiers, and jitter killers. It performs full digital sample rate conversion over a wide range of input rates using a Digital Phase-Locked Loop (PLL) to remove jitter from digital audio inputs.
The device supports multiple operating modes, including Sample Rate Conversion (SRC), AD/DA mode for bitstream conversion, and slave-VCO/VcxO modes. It features an integrated IEC 958 demodulator for AES/EBU or SPDIF signals and offers final output quantization to 16, 18, or 20 bits with optional noise shaping.
