Parameter is guaranteed through characterization only and is not tested.
Running at low frequencies (< 10 MHz sinewave), the device will still be functional but may cause phase noise degradation. Inserting a low-
noise amplifier to square up the edges is recommended at lower input frequencies.
CMOS logic levels may be used if DC coupled. For optimum phase noise performance, the reference input falling edge rate should be faster
than 80mV/ns.
