DAC1408D650
Product data sheet
10.4 Clock input
The DAC1408D650 has one differential clock input, CLKINN/CLKINP.
The DAC1408D650 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
it can also be interfaced with CML (see
internal clock domain to another one is handled by Clock Domain Interface 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.
