Connector type
2.92 mm, female
Zero output state timing constant
±600 mV, single ended signaling level to 0 V ±10 mV in ≤ 40 UI = 2.9 ns; idle state (fall time after
enable asserted)
Time constant is based on 14 Gb SAS, fibre channel and PCIe Gen4. Timing from full output to
0 V. Hold at 0 for 2 ms minimum, then return to enable. Rise time expectation is on order of 30 to
40 ps. Latency of blanking period start is not timed to anything else.
Consecutive run length amplitude
droop
<10 % maximum droop (typical)
PCIe 16 Gb standard calibration pattern: 128 bit 1, 128 bit 0, single-ended, compared to
1100 pattern amplitude

Additive Jitter. The LE320/LE160 can be configured to many conditions resulting in increased Data Dependent Jitter (DDJ) and Random Jitter (Rj), for
example in a backplane emulation configuration. The LE320 can be tuned to have < 300 fs RJ RMS and < 6 ps of DDJ.
