Testing AES/EBU to I2S Converter

Other Parts Discussed in Thread: SRC4190

I have designed an AES/EBU to I2S converter using CS8164 as the digital audio receiver and SRC4190 as a sampling rate converter to give 192kHz/24 bits at the out. I wish to find out how I can test the design with an input of 44.1kHz and 48 kHz.

Kind regards

    Hi Sidney,

    This relies on many factors of your design, but the major points for the SRC4190 is that either the input or output can be a master but only one at a time. And for a master port, the sampling frequency will be determined by what the SCKI frequency is and with that what ratio you select using the mode pins.

    Hello Justin,

    Thanks for your reply. I am using the SRC4190 input as a slave. My problem with the testing is which source can I use at the AES/EBU input for testing of the design fulfills the requirement of 192kHz/24 bits, that is to visualize the clock SCK, WS and Data

    Kind regards

    Hi Sidney,

    I'm still a little confused on what you are asking for. Are you asking for test equipment that can generate or receive AES/EBU signals? We us Audio Precision test equipment.
