Note:
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.
2. For the 13.5MHz, 16.9MHz, and 27MHz outputs
External Components
The MK0220 requires a minimum number of external components for proper operation. Decoupling
capacitors of 0.1F should be connected between VDD and GND on pins 4/5 and pins 13/12, as close to
the MK0220 as possible. A series termination resistor of 33
may be used for each clock output. The device
does not require (nor do we recommend) capacitors connected to the crystal pins. If a 2.1168 MHz crystal
is used, it must be connected as close to the chip as possible. Recommended load capacitance for the crystal
is 12pF.
