192kHz Stereo Asynchronous

Sample Rate Converters

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 Multi-

plexed (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 gen-

eration 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 Instru-

ments 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.
