SRC4184IPAG 24 位 212ksps 采样率转换器, 64针 TQFP封装

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 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.
