2 Recommended Equipment
• 5-Vdc at 0.5 A power supply
• A pattern generator capable of supplying single-ended signals at the desired signaling rate and input
levels
• A multiple-channel, high-bandwidth oscilloscope, preferably above the 100-MHz range. Differential and
single-ended oscilloscope probes
• When using two or more EVMs, a 100-Ω transmission medium between transceivers (twisted-pair
cable recommended, CAT5 cable for example) made be used using JMP7 and JMP9 (half duplex)
between EVMs. Full-duplex connections can be made using JMP5/JMP7 and JMP8/JMP9. The
termination resistors need to be configured for each case.
2.1 EVM Configurations
The schematic for the ISO1176TEVM appears on the last page of this manual.
Table 1 contains a list of the onboard jumpers and their function as well as the input and output loading
installed on the board for the half-duplex ISO1176TEVM.

These resistors are provided as impedance-matching terminations to be used when driving these
signals with 50-Ω source impedance test/measurement equipment. When not driving these signals with
a 50-Ω source, the components must be removed.
