(1) All typicals are given for: V_CC = 3.3 V, T_A = 25°C.
(2) Generator waveform for all tests unless otherwise specified: f = 1 MHz, Z_O = 50 Ω, 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 (1.05-V to 1.35-V peak to peak). Output criteria:
60 / 40% duty cycle, V_OL (maximum 0.4 V), V_OH (minimum 2.7 V), Load = 15 pF (stray plus probes).
