interpolating DAC with JESD204A interface
10.4 Clock input
The DAC1208D650 has one differential clock input, CLKINN/CLKINP.
The DAC1208D650 can operate with a clock frequency up to 312.5 MHz or up to 650 MHz
if the internal PLL is bypassed. The clock input can be LVDS (see
Figure 15
) but it can
also be interfaced with CML (see
Figure 16
). Error free data transition from one internal
clock domain to another one is handled by Clock Domain Interface (CDI) logic.
During the reset phase (RESET_N asserted), the clock must be stable and running. This
ensures a proper reset of the complete device.
The device has no embedded power-on-reset feature. Driving the RESET_N pin to set the
device to its default state is mandatory.
