External Components
Decoupling Capacitor
As with any high-performance mixed-signal IC, the
MK2703B must be isolated from system power supply noise
to perform optimally.
A decoupling capacitor of 0.01µF must be connected
between VDD and GND on pins 2 and 3. It must be
connected close to the MK2703B to minimize lead
inductance. No external power supply filtering is required for
the MK2703B.

Series Termination Resistor
A 33Ω terminating resistor can be used next to the clock
outputs for trace lengths over one inch.
Crystal Load Capacitors
The total on-chip capacitance is approximately 16 pF. A
parallel resonant, fundamental mode, AT cut 27 MHz crystal
should be used. The device crystal connections should
include pads for small capacitors from X1 to ground and
from X2 to ground. These capacitors are used to adjust the
