(1) Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced to ground
unless otherwise specified (such as V_ID).
(2) All typicals are given for: V_CC = +3.3V and T_A = +25°C.
(3) Output short circuit current (I_OS) is specified as magnitude only, minus sign indicates direction only. Only one output should be shorted
at a time, do not exceed maximum junction temperature specification.

(1) All typicals are given for: V_CC = +3.3V and T_A = +25°C.
(2) C_L includes probe and jig capacitance.
(3) 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.
(4) 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.
(5) t_SKD2 is the differential channel-to-channel skew of any event on the same device. This specification applies to devices having multiple
receivers within the integrated circuit.
(6) 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.
(7) t_SKD4, 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. t_SKD4 is defined as |Max − Min|
differential propagation delay.
(8) f_MAX generator input conditions: t_r = t_f < 1 ns (0% to 100%), 50% duty cycle, differential (1.05V to 1.35 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).
