Applications Information
Crystal Selection
When using a crystal with the MAX9471/MAX9472s’
internal oscillator, connect the crystal to X1 and X2.
Choose an AT-cut crystal that oscillates on its funda-
mental mode with ±30ppm and loading capacitance
less than 14pF. To achieve a wide VCXO tuning range,
select a crystal with motional capacitance greater than
7fF and connect 6pF or less shunt capacitors at X1 and
X2 to ground. When the VCXO is used as an oscillator,
select both shunt capacitors to be approximately 13pF.
The optimal shunt capacitors for achieving minimum
frequency offset can be determined experimentally.
Board Layout Considerations and
Bypassing
The MAX9471/MAX9472s’ oscillator frequencies make
proper layout important to ensure stability. For best per-
formance, place components as close as possible to
the device.
Digital or AC transient signals on GND can create noise
at the clock output. Return GND to the highest quality
ground available. Bypass each VDD and VDDA with a
0.1F capacitor, placed as close as possible to the
device. Careful PC board ground layout minimizes
crosstalk between the outputs and digital inputs.
