Description

SYNC

Level-Triggered Control Input (Active Low). This is the frame synchronization signal for the input

data. When SYNC goes low, it enables the input shift register, and data is transferred in on the falling

taken high before this edge, in which case the rising edge of SYNC acts as an interrupt and the write

sequence is ignored by the DAC.

SCLK

Serial Clock Input. Data is clocked into the input shift register on the falling edge of the serial clock

input. Data can be transferred at rates up to 30 MHz.

SDIN

Serial Data Input. This device has a 16-bit shift register. Data is clocked into the register on the falling

edge of the serial clock input.
