... Short Frame Sync The W681511 operates in the Short Frame Sync Mode when the Frame Sync signal at pin FST is high for one and only one falling edge of the bit-clock at the BCLKT pin. On the following rising edge of the bit-clock, the W681511 starts clocking out the data on the PCMT pin, which will also change from high to low impedance state ...
