The 5V41068A 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 5V41068A selects between 1 of 2 differential HCSL inputs to drive a single differential HCSL output pair. The output can also be terminated to LVDS.

Features

  • 1 – 0.7V current mode differential HCSL output pair
  • Low additive jitter
  • suitable for use in PCIe Gen2 and Gen3 systems
  • 16-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
  • Industrial temperature range available
  • supports demanding embedded applications
  • Additive cycle-to-cycle jitter <5 ps
  • Additive phase jitter (PCIe Gen3) <0.2ps
  • Operating frequency up to 200MHz
