1Guaranteed by desig n and characterization, not 100% tested in production.
3 Driven by PCIe output of main clock, PLL Mode or Bypass mode
2 All Long Term Accuracy specifications are guaranteed with the assumption that the input clock complies with CK410B+ accuracy requirements. The
buffer itself does not contribute to ppm error.
