Parameters guaranteed by design and characterization. Not 100% tested in production.
Note 1: It may be possible to operate the IDT9170B outside of these ranges. Consult IDT for your specific
application.
Note 2: All AC specifications are measured with a 50Ω transmission line, load teminated with 50Ω to 1.4 V.
Note 3: Duty cycle measured at 1.4 V.
Note 4: Skew measured at 1.4 V on rising edges. Positive sign indicates the first signal precedes the second signal.
