DAC1627D1G25
Dual 16-bit DAC: up to 1.25 Gsps; x2, x4 and x8 interpolating
10.6 Timing
The DAC1627D1G25 can operate at an update rate (f
s
) of up to 1.25 Gsps and with an
input data rate (f
data
) of up to 312.5 MHz.
The sampling position of the LVDS data can be tuned using a 16-step compensation delay
clock. The delay clock (see
Figure 14
, signals LDCLKPcp and LDCLKNcp) is used
internally to obtain a control signal, which enables calibrating the compensation delay at
start-up and monitoring if the sampling position is properly aligned.
Figure 14
shows how the compensation delay helps to recover the LVDS DDR data on
both the A and B paths.
