8.3.15 Frame-Sync Serial Interface

Frame-Sync format is similar to the interface often used on audio ADCs. It operates in slave fashion—the user must supply framing signal FSYNC (similar to the left/right clock on stereo audio ADCs) and the serial clock SCLK (similar to the bit clock on audio ADCs). The data are output MSB first or left-justified on the rising edge of FSYNC. When using Frame-Sync format, the FSYNC and SCLK inputs must be continuously running with the relationships shown in the Timing Requirements: Frame-Sync Format table.
