Figure 14 AC Output Test Load (I²C)
The SDA and SCL pins are open-drain drivers. Refer to the Philips I²C Specification [1] for appropriate selec-
tion of pull-up resistors for each.

Figure 15 sRIO Lanes Test Load
The characteristic impedance Z0 should be designed for 100 ohms. An in line capacitor C1 and C2 at each
input of the receiver provides AC-coupling and a DC-block. The IST recommended and test value is 100nF for
each. Thus, ant DC bias differential between the two devices on the link is negated. The differential input resis-
tance is designed to be 100 Ohms (per sRIO specification). Thus, R1 and R2 are 50 Ohms each. Note that
V_BIAS is the internal bias voltage of the device’s receiver.
