3.3V 1:10 CMOS Clock Driver
Description
Pericom Semiconductor’s PI49FCT32807 is a 3.3V very low-
skew clock buffer that produces ten outputs from a single low-
capacitance input. Excellent output signals to power and ground
ratio minimize power and ground noise, and also improves output
performance.
The PI49FCT32807 integrates series damping resistors on all
outputs.

Notes:
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 3.3V, +25°C ambient and maximum loading.
3. VOH = VCC – 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.
