Pericom Semiconductor’s PI49FCT32807 is a 3.3V very lowskew clock buffer that produces ten outputs from a single lowcapacitance input. Excellent output signals to power and ground
ratio minimize power and ground noise, and also improves output
performance.
Low skew: < 200ps
Fast switching frequency >133 MHz
Fast output rise/fall time < 1.5ns
Low propagation delay < 2.5ns
Low input capacitance < 6.0pF
5V I/O Tolerant input
Rail-to-Rail CMOS outputs
Industrial Temperature: –40°C to +85°C
3.3V ±10% operation
Packaging (Pb-free & Green Available):
– 20-pin 300-mil wide SOIC (S)
– 20-pin 150-mil wide QSOP (Q)
– 20-pin 209-mil wide SSOP (H)
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.
