Test Loads and Waveforms
Notes:
19. 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.
20. Not applicable for AC-coupled interfaces. For AC-coupled interfaces, V
requirement still needs to be satisfied.
21. Maximum I
is measured with V
= MAX, parallel outputs unloaded, RX channels enabled, and Serial Line Drivers enabled and sending a continuous
alternating 01 pattern to the associated receive channel.
22. Typical I
is measured under similar conditions except with V
= 3.3V, T
= 25°C, parallel outputs unloaded, RX channels enabled, and Serial Line Drivers
enabled and sending a continuous alternating 01 pattern to the associated receive channel.
23. 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.
24. The LVTTL switching threshold is 1.4V. All timing references are made relative to the point where the signal edges crosses the threshold voltage.
