What is the reference clock signaling type and frequency range?
• The reference clock frequency range is from 12.5 MHz to 240 MHz. The specified signaling type is LVCMOS, which means you need 0.4VDD swing and VDD/2 biasing. However, the device will work properly with only a 500 mV swing so that an LVPECL signal (one of the differential pairs) can drive the CDCF5801.
