Voltage range VR -0.3 3.6 V RLOAD = 110 Ω +/- 20% Common mode voltage(1) VC 0.05 2.4(2) V RLOAD = 110 Ω +/- 20% Differential input voltage(3) |Vi| 100 mV RLOAD = 110 Ω +/- 20% Differential input hysteresis voltage(4) |VHYS| 25 mV RLOAD = 110 Ω +/- 20% Differential input capacitance Ci 5 pF RLOAD = 110 Ω +/- 20% R Bias resistors(5) PULLUP/ 140 200 260 k Ω PULLDOWN 1. Vc is defined as the voltage that is mid-way between VH and VL. 2. This parameter is guaranteed with Vdd > 4 V. 3. |Vi| defines the minimum differential voltage that is guaranteed to be recognized as a valid input, 1 or 0, by the receiver. 4. |Vhys| defines the minimum voltage separation between the actual |Vi| rising and falling thresholds. 5. A pullup resistor is present between the minus LVDS input and V3.3, and a pulldown resistor is present between plus LVDS input and GND in order to force a ‘0’ value if the LVDS input is floating.
