Description for the SRC4194

The SRC4194 is a four-channel, asynchronous sample rate converter (ASRC), designed for professional and broadcast audio applications. The SRC4194 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 SRC4194 to interface to a wide range of audio data converters, digital audio receivers and transmitters, and digital signal processors.

The SRC4194 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 SRC4194 may be operated in Software mode, where a four-wire serial peripheral interface (SPI) port provides access to internal control and status registers.

The SRC4194 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 SRC4194 also requires a digital I/O supply, which operates from +1.65V to +3.6V. The SRC4194 is available in a TQFP-64 package.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships  tube or tray  devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
