The MK2771-16 requires a minimum number of external components for proper operation. Use a low inductance
ground plane, connect all GNDs to this. Connect 0.01µF decoupling caps on pins 5, 7, 8 and 22 directly to the
ground plane, as close to the MK2771-16 as possible. A series termination resistor of 33Ω may be used for each
clock output.The 13.500 MHz crystal must be connected as close to the chip as possible. The crystal should be a
parallel mode, pullable, with load capacitance of 14 pF. Consult ICS full specifications. Please obey Application
Note MAN05 for pullable crystal layout info except for the following: the MK2771-16 introduces a GND pin (pin #3)
between the pullable crystal pins. This ground should be brought in straight from the right side underneath the
device.
