Passive Equalization of Test Fixtures for High-Speed Digital Measurements with Automated Test Equipment
نویسندگان
چکیده
Automated test equipment (ATE) is used extensively in production test and device characterization of integrated circuits (ICs). With future devices forecasted to contain hundreds of I/O cells operating at speeds from 5Gb/s to 10Gb/s, the challenge to test those devices with an ATE system is becoming more complex. The speed bottleneck is moving from the pin electronics of the ATE to the test fixture connecting the ATE to the device under test (DUT). The layout of the test interface will require thinner and longer signal traces which will have an unacceptable loss for the required data rates. This challenge will require the use of compensation techniques to address the increased loss of the signal traces. This article presents one strategy to address this challenge by integrating passive equalization in the test-fixture signal trace.

On the Practical Aspects of Joint Passive Phase Conjugation and Equalization Underwater Communication Systems
Underwater acoustic communication systems suffer from the channel impairments which results in time spreading of the transmitted signal. In underwater environment, multiple replicas of the transmitted signal are received at the receiver through different paths, which causes significant Inter-Symbol Interference (ISI). Decision Feedback Equalizers (DFE) was utilized to overcome this type of inte...

This paper presents the characterization of a PCI-express test fixture that was created to passively probe a x16 link on a PCB. This fixture plugs into the 48-pin, midbus footprint which has been adopted by as the industry standard for observing PCIexpress links on a PCB. This fixture is used to observe signals and pass them to a piece of test equipment (TDR, VNA, or oscilloscope). Engineers re...

Serializer/deserializer (SerDes) transceivers are an increasingly popular way to reduce IC pin-count, power, electromagnetic interference, and wiring between ICs. Mainstream serial data rates are around 2.5 Gbps, with PCI-Express being the most common standard, but 5 to 10 Gbps SerDes I/Os are in many new designs. The total number of such transceivers shipped (there may be many per IC) is expec...
