Fclk is verified during the functional pattern test. Serial programming sections of the functional pattern are clocked at 10 MHz to verify Fclk
specification.
CMOS logic levels can be used to drive reference input if DC coupled. Voltage input needs to be a minimum of 0.5 Vp-p. For optimum
phase noise performance, the reference input falling edge rate should be faster than 80mV/ns.
Parameter is guaranteed through characterization only and is not tested.
