3 Description
The SRC4192 and SRC4193 devices are
asynchronous, sample-rate converters designed for
professional and broadcast audio applications. The
SRC4192 and SRC4193 devices combine a wide
input-to-output sampling ratio with outstanding
dynamic range and ultra-low distortion. Input and
output serial ports support standard audio formats, as
well as a Time Division Multiplexed (TDM) mode.
Flexible audio interfaces allow the SRC4192 and
SRC4193 devices to connect to a wide range of
audio data converters, digital audio receivers and
transmitters, and digital signal processors.
The SRC4192 device is a standalone, pin-
programmed device, with control pins for mode, data
format, mute, bypass, and low group-delay functions.
The SRC4193 device is a software-controlled device
featuring a serial peripheral interface (SPI) port,
which is utilized to program all functions through the
internal control registers.
The SRC4192 and SRC4193 devices can operate
from a single 3.3-V power supply. A separate digital
I/O supply (V_IO) operates over the 1.65-V to 3.6-V
supply range, allowing greater flexibility when
interfacing to current and future generation signal
processors and logic devices. Both devices are
available in a 28-pin SSOP package.
