3 Description
The SRC4192-Q1 device is an asynchronous,
sample-rate converter designed for professional and
broadcast audio applications. The SRC4192-Q1
device combines 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-Q1 device to connect to a wide
range of audio data converters, digital audio receivers
and transmitters, and digital signal processors.
The SRC4192-Q1 device is a standalone, pin-
programmed device, with control pins for mode, data
format, mute, bypass, and low group-delay functions.
The SRC4192-Q1 device can operate from a single
3.3-V power supply. A separate digital I/O supply
(VIO) 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. The device is available in a 28-pin SSOP
package.
