The “normalized” bandwidth equation above does not take
into account the effects of damping factor or the second
pole. However, it does provide a useful approximation of
filter performance.
The loop damping factor is calculated as follows:

IDT™ VCXO-BASED FRAME CLOCK FREQUENCY TRANSLATOR
Special considerations must be made in choosing loop
components C
found on the IDT web site.
Series Termination Resistor
Clock output traces over one inch should use series
termination. To series terminate a 50 trace (a commonly
used trace impedance), place a 33 resistor in series with
the clock line, as close to the clock output pin as possible.
The nominal impedance of the clock output is 20 . (The
I

optional series termination resistor is not shown in the

Decoupling Capacitors
As with any high performance mixed-signal IC, the
MK2059-01 must be isolated from system power supply
noise to perform optimally.
Decoupling capacitors of 0.01µF must be connected
between each VDD and the PCB ground plane. To further
guard against interfering system supply noise, the
in loop filter (Farads)
MK2059-01 should use one common connection to the PCB
power plane as shown in the diagram on the next page. The
ferrite bead and bulk capacitor help reduce lower frequency
noise in the supply that can lead to output clock phase
