IDT™ / ICS™ VCXO-BASED CLOCK TRANSLATOR WITH HIGH MULTIPLICATION 19
MK2069-03
VCXO-BASED CLOCK TRANSLATOR WITH HIGH MULTIPLICATION
Note 1: This is the recommended crystal operating range. A crystal as low as 8 MHz can be used, although this may
Note 2: The VCXO crystal will be pulled to its minimum frequency when there is no input clock (CLR = 1) due to the
Note 3: The minimum practical phase detector frequency is is assumed to be 1 kHz. Through proper loop filter
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
