Introspect Launches Protocol Analyzer for Image Sensor Development

IntrospectSV4E SVLSEC 400x275

August 25, 2021

Introspect Technology, which manufactures test and measurement tools for high-speed digital applications, has announced the SV4E-SLVSEC, a 16-lane, 6.5 Gbps SLVS-EC Protocol Analyzer. The device enables the development, debugging and testing of image sensor and camera systems based on the Scalable Low Voltage Signaling Embedded Clock (SLVS-EC) Version 2.0 protocol.

Promising the enablement of extremely high frame rate and high resolution sensing and vision solutions, the interface protocol supports high bandwidth payload transfer using a fully differential, embedded clock signaling scheme. The company said the analyzer is positioned to support future CMOS image sensor implementations, targeting automotive and robotics applications. The analog front-end technology provides high-confidence design validation at speeds far exceeding the latest SLVS-EC standards, Introspect said.

“The SLVS-EC Version 2.0 interface is establishing itself as a viable solution for a certain class of high performance CMOS image sensors that have traditionally relied on LVDS or SLVS signaling,” said Mohamed Haved, CEO of Introspect Technology. “Staying true to the Introspect tradition of supporting product engineers throughout the lifecycle of development and high-volume manufacturing, the SV4E-SVLSEC is packed with features that help at both ends of the product creation spectrum: from gaining deep insights during the debug phases to reducing test times with go/no-go testing during mass production.”

The analyzer is a completely integrated solution residing in a small form factor instrument, the size of a large smartphone or small tablet computer. The analog front end includes a linear amplifier, a continuous-time linear equalizer, a high-performance clock and data recovery (CDR) circuit, and phone phase and window comparator controls. The company said this makes it a true ATE-on-Bench solution that can be used during the early days of development, but also during end-of-line mass production testing and calibration.

With 16 lanes that are fully programmable, the SV4E-SLVSEC can also be used to test single-interface and multiple-interface image sensor topologies. Additionally, each interface topology can be configured with different lane support. This flexibility means that a single test and measurement tool can be deployed across multiple applications, helping to support fragmented roadmap strategies that are becoming more and more prevalent in modern product development paradigms, Introspect said.

Control of the device happens through the Introspect ESP Software, which aims to strike a perfect balance between ease of use and infinite programmability. For example, all capture parameters are accessible through property tables that enable one-click analysis of SVLS-EC packets and/or video frames, but also offers a comprehensive Python-based integrated development environment. This allows users to create automated tests in a matter of minutes, the company said.
