Minimum receiver eye
width
The maximum interconnect
media and transmitter jitter that
can be tolerated by the receiver
can be derived as
TRX-MAX-JITTER = 1 –
UPEEWRX = 0.6 UI.
TRX-EYE
0.4
——UI
Maximum time between
the jitter median and
maximum deviation from
the median.
Jitter is defined as the
measurement variation of the
crossing points (VPEDPPRX = 0
V) in relation to a recovered Tx
UI. A recovered Tx UI is
calculated over 3500
consecutive unit intervals of
sample data. Jitter is measured
using all edges of the 250
consecutive UI in the center of
the 3500 UI used for calculating
the Tx UI.
