Notes:
5. Guaranteed by design and characterization, not 100% tested in production
is measured at common mode voltage.
2. Output short-term jitter is the absolute value fo the worst case deviation and is
defined in the Jitter section.
3. tSKEW is the timing difference between any two of the four differential clocks and
4. Zout is defined at the output pins.
1. Max and min output clock cycle times are based on nominal output frequencies
of 400 and 667 MHz respectively. For spread spectrum modulated input clocks,
the output clocks track the input modulation.
Short term jitter (over 1 to
6 clock cycles)
