4 / 16 page ADN4667 Data Sheet Rev. B | Page 4 of 16 AC CHARACTERISTICS VCC = 3.0 V to 3.6 V; RL = 100 Ω; CL1 = 15 pF to GND; all specifications TMIN to TMAX, unless otherwise noted. All typical values are given for VCC = +3.3 V, TA = +25°C. Table 2.

Other inputs are set to GND. 5 t SKD1 = |tPHLD − tPLHD| is the magnitude difference in differential propagation delay time between the positive going edge and the negative going edge of the same channel. 6 t SKD2 is the differential channel-to-channel skew of any event on the same device. 7 t SKD3, differential part-to-part skew, is defined as the difference between the minimum and maximum specified differential propagation delays. This specification applies to devices at the same VCC and within 5°C of each other within the operating temperature range. 8 t SKD4, part-to-part skew, is the differential channel-to-channel skew of any event between devices. This specification applies to devices over recommended operating temperatures and voltage ranges, and across process distribution. tSKD4 is defined as |maximum − minimum| differential propagation delay. 9 f MAX generator input conditions: tr = tf < 1 ns (0% to 100%), 50% duty cycle, 0 V to 3 V. Output criteria: duty cycle = 45% to 55%, VOD > 250 mV, all channels switching. Test Circuits and Timing Diagrams Figure 2. Test Circuit for Driver VOD and VOS Figure 3.
