NOTES:
6. The input pins IN[P,N] are DC biased to V_DD. The specified cable input amplitude range is established by characterization and
not production tested, and is valid so long as the voltages at the input pins IN[P,N] do not violate the voltage ranges specified
in “Absolute Maximum Ratings” on page 3.
7. Maximum Reflection Coefficient given by equation SDDXX(dB) = -12 + 2*√(f), with f in GHz. Established by characterization
and not production tested.
8. Maximum Reflection Coefficient given by equation SDDXX(dB) = -6.3 + 13Log10(f/5.5), with f in GHz. Established by
characterization and not production tested.
9. Reflection Coefficient given by equation SCCXX(dB) < -7 + 1.6*f, with f in GHz. Established by characterization and not
production tested.
10. Limits established by characterization and are not production tested.
11. Output residual jitter is the difference between the total jitter at the lane extender output and the total jitter of the transmitted
signal (as measured at the input to the channel). Total jitter (T_J) is DJ_pp + 14.1 x RJ_RMS
12. Measured using a PRBS 2¹⁵-1 pattern. Deterministic jitter at the input to the lane extender is due to frequency-dependent,
media-induced loss only.
13. Rise and fall times measured using a 2GHz clock with a 20ps edge rate.
Typical Performance Characteristics
Performance is measured using the test setup illustrated in Figure 2. The signal from the pattern generator is launched
into the twin-ax cable using an SMA adapter card. The chip evaluation board is connected to the output of the cable
through another adapter card. The ISL36111 output signal is then visualized on a scope to determine signal integrity
parameters such as jitter.
