(2) Generator waveform for all tests unless otherwise specified: f = 1 MHz, ZO = 50Ω, tr and tf (0% to 100%) ≤ 3 ns for RIN. (3) tSKD2, Channel-to-Channel Skew is defined as the difference between the propagation delay of one channel and that of the others on the same chip with any event on the inputs. (4) 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. (5) tSKD1 is the magnitude difference in differential propagation delay time between the positive going edge and the negative going edge of the same channel (6) 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 |Max−Min| differential propagation delay. (7) fMAX generator input conditions: tr = tf < 1 ns (0% to 100%), 50% duty cycle, differential (1.05V to 1.35V peak to peak). Output criteria: 60/40% duty cycle, VOL (max 0.4V), VOH (min 2.7V), Load = 15 pF (stray plus probes). PARAMETER MEASUREMENT INFORMATION Figure 1.
