Notes:
23. The common mode range defines the allowable range of INPUT+ and INPUT− when INPUT+ = INPUT−. This marks the zero-crossing between the true and
complement inputs as the signal switches between a logic-1 and a logic-0.
24. Not applicable for AC-coupled interfaces. For AC-coupled interfaces, V_DIFFS requirement still needs to be satisfied.
25. Maximum I_CC is measured with V_CC = MAX, RXCKSEL = LOW, with all TX and RX channels and Serial Line Drivers enabled, sending a continuous alternating
01 pattern to the associated receive channel, and outputs unloaded.
26. Typical I_CC is measured under similar conditions except with V_CC = 3.3V, T_A = 25°C, RXCKSEL = LOW, with all TX and RX channels enabled and one Serial
Line Driver per transmit channel sending a continuous alternating 01 pattern to the associated receive channel. The redundant outputs on each channel are
powered down and the parallel outputs are unloaded.
27. Cypress uses constant current (ATE) load configurations and forcing functions. This figure is for reference only. 5-pF differential load reflects tester capacitance,
and is recommended at low data rates only.
28. The LVTTL switching threshold is 1.4V. All timing references are made relative to the point where the signal edges crosses this threshold voltage.
