DriveCable02EVK User Manual
Evaluation with 100-ohm Differential Balanced Cables
The DriveCable02EVK can be used to evaluate the chipset with 100-ohm differential cables (twin-axial
and twisted pair cables). Examples are CAT5e/6/7 cable assemblies such as Belden 1500A, Belden 1700A,
Siemon CAT7 Tera, Belden 89207 and Amphenol SKEWCLEAR series of cables. Figure 2 is a simplified
block diagram of the configuration.

Test Setup for 100-ohm Differential Cable Evaluation
Note: Connector Adapters are NOT included in this kit. Currently, RJ45-SMA adapters are
available and can be ordered separately. The part number is DS91C176EVK NOPB. If cable
assemblies have other than RJ-45 connectors, it is recommended to obtain/develop an adapter board
similar to the RJ45-SMA adapter to ensure good impedance control of the signal path. For more
information about the RJ45-SMA Adapter check:
