Clock Input and Timing
Figure 27 shows the clock and data input timing diagram for internal and external clock modes, respectively.
Note that a negative value indicates a reversal of the edge positions as shown in the timing diagram. Figure 27
also shows the delay (td) of the 1×/2× data clock (PLLLOCK) from CLK in external clock mode (typical td = 4.1
ns). The latency from data to DAC is defined by Figure 28. The DAC5674 features a differential clock input.
In internal clock mode, the internal data clock is a divided down version of the PLL clock (/2 or /4), depending
on the level of interpolation (2
× or 4×). In external mode, the internal data clock is a divided down version of
the input CLK (/2 or /4), depending on the level of interpolation (2
× or 4×). Internal edge-triggered flip-flops latch
the input word on the rising edge of the positive data clock.
