Description
The PI49FCT380x is a 3.3V compatible, high-speed, low-noise,
non-inverting clock buffer. The key goal in designing the
PI6C380x is to target networking applications that require low-
skew, low-jitter, and high-frequency clock distribution. Providing
output-to-output skew as low as 250ps, the PI49FCT380x is an
ideal clock distribution device for synchronous systems. Designing
synchronous networking systems requires a tight level of skew from
a large number of outputs.

Maximum Ratings
(Above which the useful life may be impaired. For user guidelines, not tested.)
Note:
Stresses greater than those listed under MAXIMUM
RATINGS may cause permanent damage to the
device. This is a stress rating only and functional operation
of the device at these or any other conditions above those
indicated in the operational sections of this specification is
not implied. Exposure to absolute maximum rating condi-
tions for extended periods may affect reliability.
Notes: 1. For maximum or minimum conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VDD = 3.3V, +25°C ambient and maximum loading.
3. VOH = VDD– 0.6V at rated current.
4. This parameter is determined by device characterization but is not production tested.
5. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
