1 CL includes probe and jig capacitance.
2 AC parameters are guaranteed by design and characterization.
3 Generator waveform for all tests, unless otherwise specified: f = 50 MHz, ZO = 50 Ω, tr ≤ 1 ns, and tf ≤ 1 ns.
4 All input voltages are for one channel, unless otherwise specified. Other inputs are set to GND.
5 tSKD1 = |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 tSKD2 is the differential channel-to-channel skew of any event on the same device.
7 tSKD3, 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 tSKD4, part-to-part skew, is the differential channel-to-channel skew of any event between devices. This specification applies to devices over the recommended operating
temperature and voltage ranges, and across process distribution. tSKD4 is defined as |maximum − minimum| differential propagation delay.
9 fMAX 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.
