3 Description
The SRC4190 device is an asynchronous sample rate converter designed for professional and broadcast audio applications. The SRC4190 combines a wide input-to-output sampling ratio with outstanding dynamic range and 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 SRC4190 to connect to a wide range of audio data converters, digital audio receivers and transmitters, and digital signal processors. The SRC4190 is a standalone pin-programmed device, with control pins for mode, data format, mute, bypass, and low group delay functions. The SRC4190 may be operated from a single 3.3-V power supply. A separate digital I/O supply (VIO) operates with a 1.65-V to 3.6-V supply, allowing greater flexibility when interfacing to current and future generation signal processors and logic devices. The SRC4190 is available in a 28-pin SSOP package.

7 Detailed Description
7.1 Overview
The SRC4190 device is an asynchronous sample rate converter (ASRC) designed for professional audio applications. Operation at input and output sampling frequencies up to 212 kHz is supported, with an input-to- output sampling ratio from 16:1 to 1:16. Excellent dynamic range and total harmonic distortion plus noise (THD+N) are achieved by employing high performance and linear phase digital filtering. Digital filtering options allow for lower group delay processing. The audio input and output ports support standard audio data formats, as well as a TDM interface mode. 24-, 20-, 18-, and 16-bit word lengths are supported. Both ports may operate in slave mode, deriving their word and bit clocks from external input and output devices. Alternatively, one port may operate in master mode while the other remains in slave mode. In master mode, the LRCK and BCK clocks are derived from the reference clock input (RCKI). The flexible configuration of the input and output ports allows connection to a wide variety of audio data converters, interface devices, digital signal processors, and programmable logic. A bypass mode is included, which allows audio data to be passed directly from the input port to the output port, bypassing the ASRC function. The bypass option is useful for passing through encoded or compressed audio data, or nonaudio control or status data. A soft mute function is available providing artifact-free operation while muting the audio output signal. The mute attenuation is typically –128 dB. The output port data is clocked by either the audio data source in slave mode, or by the SRC4190 in master mode. The input data is passed through interpolation filters which up-sample the data, which is then passed on to the re-sampler. The rate estimator compares the input and output sampling frequencies by comparing LRCKI, LRCKO, and a reference clock. The results include an offset for the FIFO pointer and the coefficients needed for re-sampling function. The output of the re-sampler is then passed on to the decimation filter. The decimation filter performs down-sampling and anti-alias filtering functions.
