General Digital Input (GDIN)
TDA1373H
GENERAL DESCRIPTION
The TDA1373H is a General Digital Input (GDIN) device
for audio signals which is able to perform a high-quality
sample rate conversion of digital audio signals (
SRC
mode
). The device reads several serial input formats and
signals in the IEC 958 digital audio format (also known as
AES/EBU or SPDIF signals). For this purpose a full Audio
Digital Input Circuit (ADIC) is present in the device.
An internal digital PLL results in extensive jitter removal
from incoming digital audio signals without any analog
loop electronics. The standard 20 bit output word length
can be limited to 16 or 18 bits by means of ‘in-audio-band
noise shaping’.
The GDIN digital filters can also be reused for Bitstream
ADC and DAC conversion (
AD/DA mode
). The internal
digital PLL can be reconfigured to operate the GDIN in a
slave mode, where the output sample frequency of the
device is locked to the incoming sample rate
(
SLAVE-VCO
and
SLAVE-VCXO
modes).
The combination of an ADIC function, sample rate
conversion and Bitstream ADC and DAC results in a
device with a highly versatile functionality and large
replacement value in consumer and professional
audio sets.
