Required Specifications

1. When the true and complement LVDS outputs (having

a 75

Ω connected between outputs) are connected to

3.75 k

Ω resistors and the common point of those 3.75

k

Ω resistors are connected to a voltage source that

maintained (see Figure 1).

2. When the true and complement LVDS outputs (having

a 5 pF capacitor attached between outputs) are con-

nected with 37.5

Ω resistors each to common point,

then the common point does not vary by more than 150

mV under all process, temperature and voltage condi-

tions when the outputs switch either from LOW-to-

HIGH or from HIGH-to-LOW (see Figure 2).

4. Fail safe protection on the outputs that draw less than

20

µA of current (worst case) on the LVDS inputs. In

this condition, if the input is in fail safe selected to

from being amplified when the connection is broken.
