VCXO-Based Clock Translator with High Multiplication
Description
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.
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.
Features
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
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.
