How do I use level translators to interface to LVTTL or CMOS I/Os for the MAX11300?
Refer to the MAX11300 Configuration Software tool and use the function "Level Translator" and set the Input Threshold and Output Levels to match the switching thresholds for the signal types. For example, LVTTL Input: for 3.3V LVTTL VOH = 2.4V, VOL = 0.4V, VIH = 2.0V and VIL = 0.8V with VT = 1.5V MOS Output: for 5V CMOS VOH = 4.44V, VOL = 0.7V, VIH = 0.7 × VCC = 3.5V and VIL = 0.3 × VCC = 1.5V with VT = 2.5V. In this case, set the Input Threshold of the PIXI port = 1.5V and Output Level of the PIXI port = 5V.
