(1) All typicals are given for: V_CC = +3.3V, T_A = +25°C.
(2) Generator waveform for all tests unless otherwise specified: f = 1 MHz, Z_O = 50Ω, t_r and t_f (0% to 100%) ≤ 3 ns for R_IN.
(3) t_SKD2, 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) t_SKD3, part to part skew, is the differential channel-to-channel skew of any event between devices. This specification applies to devices
at the same V_CC, and within 5°C of each other within the operating temperature range.
(5) t_SKD1 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_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 temperature and voltage ranges, and across process distribution. t_SKD4 is defined as |Max−Min| differential
propagation delay.
(7) f_MAX generator input conditions: t_r = t_f < 1 ns (0% to 100%), 50% duty cycle, differential (1.05V to 1.35V peak to peak). Output criteria:
60/40% duty cycle, V_OL (max 0.4V), V_OH (min 2.7V), Load = 15 pF (stray plus probes).
