(1) All typical values are at 25

°C and with a 3.3-V supply.

(2) tsk(p) is the magnitude of the time difference between the tPLH and tPHL.

(3) tsk(pp) is the magnitude of the difference in propagation delay times between any specified terminals of two devices when both devices

operate with the same supply voltages, at the same temperature, and have identical packages and test circuits.

(4) Jitter parameters are ensured by design and characterization. Measurements are made with a Tektronix TDS6604 oscilloscope running

Tektronix TDSJIT3 software. Agilent E4862B stimulus system jitter 2 ps tjit(per), 16 ps tjit(cc), 25 ps tjit(pp), and 10 ps tjit(det) has been

subtracted from the values.

(5) VID = 200 mV, 50% duty cycle, VIC = 1.2 V, tr = tf ≤ 25 ns (20% to 80%), measured over 1000 samples.

(6) VID = 200 mV, 50% duty cycle, VIC = 1.2 V, tr = tf ≤ 25 ns (20% to 80%).

(7) VID = 200 mV, VIC = 1.2 V, tr = tf ≤ 0.25 ns (20% to 80%), measured over 100k samples.

(8) VID = 200 mV, VIC = 1.2 V, tr = tf ≤ 0.25 ns (20% to 80%). Deterministic jitter is sum of pattern dependent jitter and pulse width distortion.
