Description
Serial Data Input. The 16-bit serial data-word is applied to this input.
Serial Clock Input. Data is clocked into the AD9834 on each falling SCLK edge.
Active Low Control Input. This is the frame synchronization signal for the input data. When FSYNC is taken low, the
internal logic is informed that a new word is being loaded into the device.
Logic Output. The comparator output is available on this pin or, alternatively, the MSB from the NCO can be output
on this pin. Setting Bit OPBITEN in the control register to 1 enables this output pin. Bit SIGN/PIB determines
whether the comparator output or the MSB from the NCO is output on the pin.
