Switch Signal Integrity Requirements and Test Procedures for 5.0 Gb/s
Signal integrity requirements for 5.0 Gb/s applications of the switch are specifi ed. Also included are the requirements of
the test fi xture for switch S-parameter measurements.
Signal Integrity Requirements
The procedures outlined in ANSI Electronics Industry Alliance (EIA) standards documents shall be followed:
• EIA 364-101 – Attenuation Test Procedure for Electrical Connectors, Sockets, Cable Assemblies or Interconnection
Systems
• EIA 364-90 – Crosstalk Ratio Test Procedure for Electrical Connectors, Sockets, Cable Assemblies or Interconnection
Systems
• EIA 364-108- Impedance, Refl ection Coeffi cient, Return Loss, and VSWR Measured in the Time and Frequency Do-
main Test Procedure for Electrical Connectors, Sockets, Cable Assemblies or Interconnection Systems
Signal Integrity Requirements and Test Procedures for 5.0 Gb/s
Notes:
1. The specifi ed S parameters requirements are for switch component only, not including the test fi xture effect. While the TRL calibration method is
recommended, other calibration methods are allowed.

Procedure
EIA 364-101
The EIA standard shall be used with the following considerations:
1. The measured differential S parameter shall be referenced to a
100 ohms differential impedance.
2. The test fi xture shall meet the test fi xture requirement defi ned in
Section 1.12.
3. The test fi xture effect shall be removed from the measured S
parameters. Refer to Note 1.
EIA 364-108
The EIA standard shall be used with the following considerations:
1. The measured differential S parameter shall be referenced to a
100 ohms differential impedance.
2. The test fi xture shall meet the test fi xture requirement in Section
1.12.
3. The test fi xture effect shall be removed. Refer to Note 1.
Intra-pair skew must be achieved by design; measurement not
required.
EIA 364-90
The EIA standard must be used with the following considerations:
1. The crosstalk requirement is with respect to all the adjacent dif-
ferential pairs
