board to match the nominally required crystal load
capacitance. Because load capacitance can only be
increased in this trimming process, it is important to keep
stray capacitance to a minimum by using very short PCB
traces (and no via’s) been the crystal and device.
In most cases the load capacitors will not be required. They
should not be stuffed on the prototype evaluation board as
the indiscriminate use of these trim capacitors will typically
cause more crystal centering error than their absence. If the
need for the load capacitors is later determined, the values
will fall within the 1-4 pf range. The need for, and value of,
these trim capacitors can only be determined at prototype
evaluation. Please refer to MAN05 for the procedure to
determine the component values.
PCB Layout Recommendations
For optimum device performance and lowest output phase
noise, the following guidelines should be observed. Please
also refer to the Recommended PCB Layout drawing on
page 7.
1) Each 0.01F decoupling capacitor should be mounted on
the component side of the board as close to the VDD pin as
possible. No vias should be used between decoupling
capacitor and VDD pin. The PCB trace to VDD pin should
be kept as short as possible, as should the PCB trace to the
ground via. Distance of the ferrite bead and bulk decoupling
from the device is less critical.
2) The loop filter components must also be placed close to
the CHGP and VIN pins. CP should be closest to the device.
Coupling of noise from other system signal traces should be
minimized by keeping traces short and away from active
signal traces. Use of vias should be avoided.
3) The external crystal should be mounted just next to the
device with short traces. The X1 and X2 traces should not
be routed next to each other with minimum spaces, instead
they should be separated and away from other traces.
4) To minimize EMI, the 33
series termination resistor (if
needed) should be placed close to the clock output.
5) An optimum layout is one with all components on the
same side of the board, minimizing vias through other signal
layers (the ferrite bead and bulk decoupling capacitor can be
mounted on the back). Other signal traces should be routed
away from the MK2058-01. This includes signal traces just
underneath the device, or on layers adjacent to the ground
plane layer used by the device.
The IDT Applications Note MAN05 may also be referenced
for additional suggestions on layout of the crystal section.
