IDT5V41067A Datasheet, PDF (1/13 Pages) Integrated Device Technology – 20-pin TSSOP package

2:4 PCIE GEN1/2/3 CLOCK MULTIPLEXER
DATASHEET
IDT5V41067A
Description
The IDT5V41067A is a 2:4 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
IDT5V41067A selects between 1 of 2 differential HCSL
inputs to fanout to 4 differential HCSL output pairs. The
outputs can also be terminated to LVDS.
Recommended Applications
• Clock muxing in PCIe Gen2 and Gen3 applications
Output Features
• 4 – 0.7V current mode differential HCSL output pairs
Features/Benefits
• Low additive jitter; suitable for use in PCIe Gen2 and
Gen3 systems
• 20-pin TSSOP package; small board footprint
• Outputs can be terminated to LVDS; can drive a wider
variety of devices
• OE control pin; greater system power management
