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.

SUPPORTS 24-, 20-, 18-, or 16-BIT INPUT AND

OUTPUT DATA:

− All Output Data is Dithered from the Internal

28-Bit Data Path

SERIAL PERIPHERAL INTERFACE (SPI) PORT

SUPPORTS REGISTER READ AND WRITE

OPERATIONS IN SOFTWARE MODE

BYPASS MODE:

− Routes Input Port Data Directly to the Output

Port

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.

FOUR GROUP DELAY OPTIONS FOR THE

INTERPOLATION FILTER

DIRECT DOWNSAMPLING OPTION FOR THE

DECIMATION FILTER

DIGITAL DE-EMPHASIS FILTER:

− User-Selectable for 32kHz, 44.1kHz, and

48kHz Sampling Rates

The SRC4184 operates from either a +1.8V core supply or

a +3.3V core supply. When operating from +3.3V, the

+1.8V required by the 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.

SOFT MUTE FUNCTION

PROGRAMMABLE DIGITAL OUTPUT

ATTENUATION (SOFTWARE MODE ONLY):

− 256 Steps: 0dB to −127.5dB with 0.5dB Steps
