IDT5V41068A Datasheet, PDF (1/13 Pages) Integrated Device Technology – 16-pin TSSOP package

2:1 PCIE GEN1/2/3 CLOCK MULTIPLEXER
DATASHEET
IDT5V41068A
Description
The IDT5V41068A is a 2:1 differential clock mux for PCI
Express applications. It has very low additive jitter making it
suitable for use in PCIe Gen2 and Gen3 systems. The
IDT5V41068A selects between 1 of 2 differential HCSL
inputs to drive a single differential HCSL output pair. The
output can also be terminated to LVDS.
Recommended Applications
• Clock muxing in PCIe Gen2 and Gen3 applications
Output Features
• 1 – 0.7V current mode differential HCSL output pair
Features/Benefits
