MHz All channels switching

1 CL includes probe and jig capacitance.

2 All typicals are given for VCC = 3.3 V, TA = 25°C.

3 Generator waveform for all tests unless otherwise specified: f = 1 MHz, ZO = 50 Ω, tTLH and tTHL (0% to 100%) ≤ 3 ns for RINx+, RINx−.

4 tSKD1 is the magnitude difference in differential propagation delay time between the positive going edge and the negative going edge of the same channel.

5 Channel-to-channel skew, tSKD2, is the defined as the difference between the propagation delay of one channel and the propagation delay of the other channel on the

same chip with any event on the inputs.

6 tSKD3, part-to-part skew, is the differential channel-to-channel skew of any event between devices. This specification applies to devices at the same VCC and within 5°C of

each other within the operating temperature range.

7 tSKD4, part-to-part skew, is the differential channel-to-channel skew of any event between devices. This specification applies to devices over recommended operating

temperature and voltage ranges, and across process distribution. tSKD4 is defined as |maximum − minimum| differential propagation delay.

8 fMAX generator input conditions: f = 200 MHz, tTLH = tTHL < 1 ns (0% to 100%), 50% duty cycle, differential (1.05 V to 1.35 V peak-to-peak). Output criteria: 60%/40% duty

cycle, VOL (maximum 0.4 V), VOH (minimum 2.7 V), load = 15 pF (stray plus probes).
