Electrical Specifications

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.

External Components

A minimum number of external components are required for proper operation. A decoupling capacitor of

0.01 uF should be connected between VDD and GND on pins 4 and 6, and 16 and 14. Other VDDs and

GNDs can be connected to these pins or directly to their respective power planes. A 33

Ω series terminating

resistor may be used on the clock output if the trace is longer than 1-inch.

The crystal should be a fundamental mode (do not use third overtone), parallel resonant, with accuracy as

required by the application. Crystal capacitors should be connected from pins X1 to ground and X2 to

should be used. For a clock input, connect it to X1/ICLK, and leave X2 unconnected (floating).
