NOTE on the pins assignment. Configuration 1 In this configuration, the DUT uses the U8903B internal reference clock source as the reference clock. The DUT receives the clock references and data from the U8903B. Press on the FUNCTION panel to switch between audio generator or audio analyzer mode, and press on the FUNCTION panel to switch to digital interface.
Page 567: Configuration 2
In this configuration, the DUT uses an external master clock as the reference clock. The U8903B receives the data, frame sync, and bit clock from the DUT. A typical application for this configuration is analog to digital converter (ADC) evaluation.
Page 568: Configuration 3
In this configuration, an external master clock is used to synchronize the DUT and U8903B. A phase-locked loop (PLL) is used in the U8903B to lock the incoming master clock and regenerate the frame sync and bit clock. Data will be clocked in on each bit clock.
