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
IO
)
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.
