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 is assumed to be 1 kHz. Through proper loop filter
design lower input frequencies may be possible. Input frequencies as low as 400Hz have been
implemented.
Note 4: The output of RCLK is a positive pulse with a duration equal to VCLK high time, or half the VCLK period.
Note 5: Referenced to ICLK, the skews of VCLK, RCLK and TCLK increase together when leakage is present in the
external VCXO PLL loop filter.
