DESCRIPTION
The SRC4192 and SRC4193 are asynchronous sample rate
converters designed for professional and broadcast audio
applications. The SRC4192 and SRC4193 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 to connect to a wide range of audio
data converters, digital audio receivers and transmitters, and
digital signal processors.
The SRC4192 is a standalone pin programmed device, with
control pins for mode, data format, mute, bypass, and low
group delay functions. The SRC4193 is a software-controlled
device featuring a serial peripheral interface (SPI) port, which
is utilized to program all functions via internal control registers.
The SRC4192 and SRC4193 may be operated from a single
+3.3V power supply. A separate digital I/O supply (V
operates over the +1.65V to +3.6V supply range, allowing
greater flexibility when interfacing to current and future generation signal processors and logic devices. Both the
SRC4192 and SRC4193 are available in a 28-lead SSOP
package.

ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may be
more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
