Notes:

1. Internally AC coupled and terminated (100 Ohm differential). These levels are compatible with CML and LVPECL voltage swings.

3. 20%-80% Rise and Fall times measured with a 500 MHz signal utilizing a 1010 data pattern.

4. Contributed DJ is measured on an oscilloscope in average mode with 50% threshold and K28.5 pattern.

5. Contributed RJ is calculated for 1E-12 BER by multiplying the RMS jitter (measured on a single rise or fall edge) from the oscilloscope by 14. Per

the FC-PI standard (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.

6. In a network link, each component’s output jitter equals each component’s input jitter combined with each component’s contributed jitter.

Contributed DJ adds in a linear fashion and contributed RJ adds in a RMS fashion. In the Fibre Channel specification, there is a table specifying the

input and output DJ and TJ for the receiver at each data rate. In that table, RJ is found from TJ –DJ, where the RX input jitter is noted as Gamma R,

and the RX output jitter is noted as Delta R. The AFBR-5921ALZ contributed jitter is such that, if the maximum specified input jitter is present, and is

combined with our maximum contributed jitter, then we meet the specified maximum output jitter limits listed in the FC-PI MM jitter specification

table.
