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.
2. With a MicroClock approved pullable crystal.
External Components
The MK27273 requires a minimum number of external components for proper operation. A decoupling
capacitor of 0.01F should be connected between VDD and GND on pins 2 and 4, as close to the
MK27273 as possible. A series termination resistor of 33
may be used for the clock output. The input
crystal must be connected as close to the chip as possible. The input crystal should be a parallel mode,
pullable, AT cut, 13.5 MHz, with 14 pF load capacitance. Consult MicroClock for recommended suppliers.
IMPORTANT - read application note MAN05 before laying out the PCB.
