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.

11. Rise and fall times measured using a 2GHz clock with a 20ps edge rate and with de-emphasis disabled.

UNITS NOTES

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.
