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 ACLK at 12.288 MHz.
3. With a recommended crystal.
External Components/Crystal Selection
The MK2772-01 requires a minimum number of external components for proper operation. Decoupling capacitors
of 0.1F should be connected between VDD (pin 15) and GND (14), and between VDD (4) and GND (7), as close to
the MK2772-01 as possible. A series termination resistor of 33
may be used for each clock output. The input
crystal must be connected as close to the chip as possible.
For the VCXO to operate correctly, a crystal properly specified and matched to the MK2772-01 must be used. For
more information, including a list of recommended crystals, refer to application note MAN05.
