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.
