PIN DESCRIPTIONS

All device inputs and outputs are LP-HCSL unless described otherwise. The Type column uses the following symbols:

• I: Input

• IPD: Input with 100 kΩ internal pull-down resistor

• O: Output

• P: Power supply

The descriptions of the pins are listed in Table 3-1 and Table 3-2.

Differential/Single Ended Input Reference

Input frequency range >0 Hz to 250 MHz.

Note 1: >0 Hz means frequency higher than DC. On the power up, the

device needs four clock cycles before the outputs get enabled. This feature

filters any initial glitch or runt pulse from the clock source.

Note 2: The differential input has hysteresis of 30 mV that prevents outputs

from randomly toggling when both p and n inputs are at the same voltage

level. For example, when p and n inputs are held low as in the case when

the buffer is driven from an HCSL driver that is disabled.
