NOTES:
6. Maximum Reflection Coefficient given by equation SDDXX(dB)= -12 + 2*√(f ), with f in GHz. Established by characterization
and not production tested.
7. 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.
8. Limits established by characterization and are 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. Measured using a PRBS 2¹⁵-1 pattern.
11. Rise and fall times measured using a 2GHz clock with a 20ps edge rate and with de-emphasis disabled.
Typical Performance Characteristics
Performance is measured using the test setup illustrated in Figure 2. The signal from the pattern generator is launched
into the chip evaluation board. The ISL35111 output signal is then visualized on a scope to determine signal integrity
parameters such as jitter.
