Single/Dual LVDS Line Drivers with

Ultra-Low Pulse Skew in SOT23

AC CHARACTERISTICS (continued)

(VCC = +3.0V to +3.6V, RL = 100Ω ±1%, CL = 5pF, TA = -40°C to +85°C, unless otherwise noted. Typical values are at VCC = +3.3V,

TA = +25°C.) (Notes 3, 4, 5; Figures 2, 3)

Note 1: Maximum and minimum limits over temperature are guaranteed by design. Devices are production tested at TA = +25°C.

Note 2: By definition, current into the device is positive and current out of the device is negative. Voltages are referred to device

ground except VOD.

Note 3: AC parameters are guaranteed by design and characterization.

Note 4: CL includes probe and fixture capacitance.

Note 5: Signal generator conditions for dynamic tests: VOL = 0, VOH = 3V, f = 20MHz, 50% duty cycle, RO = 50Ω, tR ≤ 1ns, and tF ≤

1ns (0 to 100%).

Note 6: tSKD1 is the magnitude difference of differential propagation delays in a channel; tSKD1 = | tPHLD - tPLHD |.

Note 7: tSKD2 is the magnitude difference of the tPLHD or tPHLD of one channel and the tPLHD or tPHLD of the other channel on the

same device (MAX9112).

Note 8: tSKD3 is the magnitude difference of any differential propagation delays between devices at the same VCC and within 5°C

of each other.

Note 9: tSKD4 is the magnitude difference of any differential propagation delays between devices operating over the rated supply

and temperature ranges.

Note 10: fMAX signal generator conditions: VOL = 0, VOH = +3V, frequency = 250MHz, tR ≤ 1ns, tF ≤ 1ns (0 to 100%) 50% duty cycle.

Transmitter output criteria: duty cycle = 45% to 55%, VOD ≥ 250mV.

Typical Operating Characteristics

(VCC = +3.3V, RL = 100Ω, CL = 5pF, VIH = +3V, VIL = GND, fIN = 20MHz, TA = +25°C, unless otherwise noted.) (Figures 2, 3)
