DESCRIPTION
The SRC4184 is a four-channel, asynchronous sample
rate converter (ASRC), designed for professional and
broadcast audio applications. The SRC4184 combines a
wide input-to-output sampling ratio with outstanding
dynamic range and ultra low distortion. The input and
output serial ports support the most common audio data
formats, as well as a time division multiplexed (TDM)
format. This allows the SRC4184 to interface to a wide
range of audio data converters, digital audio receivers and
transmitters, and digital signal processors.
The SRC4184 may be operated in Hardware mode as a
standalone pin-programmed device, with dedicated
control pins for serial port mode, audio data format, soft
mute, bypass, and digital filtering functions. Alternatively,
the SRC4184 may be operated in Software mode, where
a four-wire serial peripheral interface (SPI) port provides
access to internal control and status registers.
The SRC4184 operates from either a +1.8V core supply or
a +3.3V core supply. When operating from +3.3V, the
+1.8V requir e d b y t h e core logic is derived from an internal
voltage regulator. The SRC4184 also requires a digital I/O
supply, which operates from +1.65V to +3.6V. The
SRC4184 is available in a TQFP-64 package.

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 t o damage because very small parametric changes could
cause the device not to meet its published specifications.
This integrated circuit can be damaged by ESD. Texas
Instruments recommends that all integrated circuits be
handled with appropriate precautions. Failure to observe
