External Components
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 0.01F 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 33
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.
