The IDT6V31021 is a 4-output low- power differential buffer. Each output has its own OE# pin. It has a maximum operating frequency of 167 MHz and supports all SERDES clock frequencies for Freescale QorIQ CPUs.


  • 4 - low power differential output pairs
  • Individual OE# control of each output pair
  • Low power differential outputs
  • Power down mode when all OE# are high
  • Industrial temperature range
  • 20-pin MLF
  • Output cycle-cycle jitter <15 ps additive
  • Output to Output skew: <50 ps
  • PCIe Gen3 addtive phasejitter <0.3 ps rms
  • 10.3125G / 64 additive phase jitter <100 fs rms
