Notes:
1. Internally ac coupled and terminated (100 Ohm differential). These levels are compatible with CML and LVPECL.
2. Internally ac coupled with internal 50 W pull-ups to V_CC (single-ended) and a required external 100 Ohm differential load termination.
3. Contributed DJ is measured on an oscilloscope in average mode with 50% threshold and K28.5 pattern
4. Contributed RJ is calculated for 1x10^-12 BER by multiplying the RMS jitter (measured on a single rise or fall edge) from the oscilloscope by 14. Per FC-
PI (Table 13 - MM jitter output, note 1), the actual contributed RJ is allowed to increase above its limit if the actual contributed DJ decreases below
its limits, as long as the component output DJ and TJ remain within their specified FC-PI maximum limits with the worst case specified component
jitter input.
5. 20%-80% electrical rise & fall times measured with a 500 MHz signal utilizing a 1010 data pattern.
