Note 1: This is the recommended crystal operating range. A crystal as low as 8 MHz can be used, although this may
result in increased output phase noise.
Note 2: The VCXO crystal will be pulled to its minimum frequency when there is no input clock (CLR = 1) due to the
attempt of the PLL to lock to 0 Hz.
Note 3: The minimum practical phase detector frequency is 1 kHz. Through proper loop filter design lower input
frequencies may be possible. Input frequencies as low as 400 Hz have been tested.
Note 4: A higher input clock frequency can be used when RPV divider = 8.
Note 5: The output of RCLK is a positive pulse with a duration equal to VCLK high time, or half the VCLK period.
Note 6: Referenced to ICLK, the skews of VCLK, RCLK and TCLK increase together when leakage is present in the
external VCXO PLL loop filter.
