A “normalized” PLL loop bandwidth may be calculated as
follows:
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:
Where:
RS = Value of resistor in loop filter (Ohms)
ICP = Charge pump current (amps)
(refer to Charge Pump Current Table, below)
N = Crystal multiplier shown in the above table
CS = Value of capacitor C1 in loop filter (Farads)
As a general rule, the following relationship should be
maintained between components C1 and C2 in the loop
filter:
Charge Pump Current Table
Special considerations must be made in choosing loop
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
optional series termination resistor is not shown in the
External Component Schematic.)
Decoupling Capacitors
As with any high-performance mixed-signal IC, the
MK2058-01 must be isolated from system power supply
noise to perform optimally.
Decoupling capacitors of 0.01F must be connected
between each VDD and the PCB ground plane. To further
guard against interfering system supply noise, the
MK2058-01 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
modulation.
Recommended Power Supply Connection for
Optimal Device Performance
Crystal Load Capacitors
The device crystal connections should include pads for
small capacitors from X1 to ground and from X2 to ground,
shown as CL in the External Component Schematic. These
capacitors are used to adjust the stray capacitance of the
