Notes:
12. VDIF (AC) is the minimum differential HSTL input voltage swing required to maintain AC characteristics including tkpd and device-to-device skew
13. 50% duty cycle; standard load; differential operation
14. For 3.3V supplies. Jitter measured differentially using an Agilent 8133A Pulse Generator with an 8500A LeCroy Wavemaster Oscilloscope using at least 10,000
data points.
15. Output pulse skew is the absolute difference of the propagation delay times: | tPLH – tPHL |.
