Electrical Specifications
Notes:
1. Stresses beyond those listed under Absolute Maximum Ratings could cause permanent damage to the device. Prolonged
exposure to levels above the operating limits but below the Absolute Maximums may affect device reliability.
External Components
The MK2751-33 requires a minimum number of external components for proper operation. Decoupling
capacitors of 0.1F should be connected between VDD and GND (pins 4 and 5, and 13 and 11), as close
to the MK2751 as possible. A series termination resistor of 33
may be used for each clock output. If a
clock input is not used, a fundamental mode 27.00 MHz crystal must be connected as close to the chip as
possible. Crystal capacitors should be connected from pins X1 to ground and X2 to ground. The value (in
pF) of these crystal capacitors should be = (CL-12)*2, where CL is the crystal load capacitance in pF. So for
a crystal with 16 pF load capacitance, the crystal capacitors should be 8 pF each.
