Description
Providing five low-skew clocks, the PI6C2305-1 is a 3.3V zero-delay
buffer designed to distribute clock signals in applications including
PC, workstation, datacom, telecom, and high-performance systems.
The PI6C2305-1 provides 5 copies of clocks that have less than
350ps propagation delay compared to a reference clock. The skew
among the output clock signals for PI6C2305-1 is less than 250ps.
When there are no rising edges on the REF input, the PI6C2305-1
enters a power-down state. In this mode, the PLL is off and all outputs
are three-stated. This results in less than 50µA of current draw.
Featuring faster rise and fall times, the PI6C2305-1H is the high-drive
version of the PI6C2305-1.
