Typical Error-Free Area
The graph in Figure 5 shows the typical error-free area
of a 223 – 1 Pseudo-Random Bit Stream (PRBS) "eye"
pattern. Data is provided for both time and voltage
domains of the differential DIN0 to DOUT0 data path for
various data rates. An interference pattern was applied
to all other inputs in parallel to induce worst-case cross
talk.
For the time domain, Peak-to-Peak Jitter was measured
at the eye crossing.
An error-free percentage value was computed using the
following formula:
(Data_Period - PPJitter) x 100 / Data_Period
Voltage values are referenced to an initial inner eye
measurement at 400 MBs. Subsequent percentage
values were computed using the following formula:
VINNER x 100 / VINNER @ 400 MBs
