SBAS082G – FEBRUARY 1998 – REVISED SEPTEMBER 2009 DIGITAL INTERFACE Timing The serial interface is synchronous and controlled by the SCLK input. The DAC1220 latches incoming bits on the falling edge of SCLK, and shifts outgoing bits on the rising edge of SCLK. An external interface should shift outgoing bits on the rising edge of SCLK, and latch incoming bits on the falling edge of SCLK. The relevant waveforms are illustrated in the timing diagrams (see Figure 7 to Figure 11). Timing numbers are given in Table 2 through Table 4. Figure 7. XIN Clock Timing Table 2.
