VCXO-Based Clock Translator with High Multiplication  
Description  
Features  
The MK2069-03 is a VCXO (Voltage Controlled Crystal  
Oscillator) based clock generator that offers system  
synchronization, jitter attenuation and frequency  
translation. It can accept an input clock over a wide  
range of frequencies and produces a de-jittered, low  
phase noise clock output. The device is optimized for  
user configuration by providing access to all major PLL  
divider functions. No power-up programming is needed  
as configuration is pin selected. External VCXO loop  
filter components provide an additional level of  
performance tailoring.  
Wide range VCXO PLL feedback divider allows high  
frequency multiplication ratios and the input of very  
low input reference frequencies  
Input clock frequency of <1kHz to 13.5MHz  
Output clock frequency of 500kHz to 160MHz  
PLL lock status output  
VCXO-based clock generation offers very low jitter  
and phase noise generation, even with low frequency  
or jittery input clock.  
PLL Clear function (CLR input) allows the VCXO to  
free-run, offering a short term holdover function.  
2nd PLL provides frequency translation of VCXO  
The MK2069-03 features a very wide range VCXO PLL  
feedback divider, allowing high frequency multiplication  
ratios and therefore the input of very low input  
reference frequencies. The lock detector (LD) output  
serves as a clock status monitor. The clear (CLR) input  
enables rapid synchronization to the phase of a newly  
selected input clock, while eliminating the generation of  
extra clock cycles and wander caused by memory in  
the PLL feedback divider. CLR also serves as a  
temporary holdover function when kept low.  
PLL to higher or alternate output frequencies.  
Device will free-run in the absence of an input clock  
(or stopped input clock) based on the VCXO  
frequency pulled to minimum frequency limit.
