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.

●DIRECT DOWNSAMPLING OPTION FOR DECIMATION FILTER (SRC4193 ONLY)

●SPI PORT PROVIDES ACCESS TO INTERNAL CONTROL REGISTERS (SRC4193 ONLY)

●SOFT MUTE FUNCTION

●BYPASS MODE

●PROGRAMMABLE DIGITAL OUTPUT ATTENUATION (SRC4193 ONLY)

256 steps: 0dB to –127.5dB, 0.5dB/step

(1)Patents Pending.

(2)Refer to the Applications Information section of this data sheet for details.

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 (VIO) 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.

PACKAGE/ORDERING INFORMATION

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.
