STMicroelectronics adds QML-V space-grade quad LVDS receiver

STMicroelectronics has expanded its space-grade portfolio with the RHFLVDS42, a QML-V qualified quad LVDS receiver for aerospace systems. The part targets higher-speed links, lower power use, and stronger radiation and ESD protection for space applications.

Why it matters: - The RHFLVDS42 is built for space systems that need faster data links, lower power draw, and stronger protection against radiation and electrical stress. - QML-V is the highest quality and reliability qualification for space-grade semiconductor components. - The part is aimed at aerospace supply chains that need a component built for long mission life and harsh environments.

What happened: - STMicroelectronics introduced the RHFLVDS42, a QML-V qualified quad low-voltage differential signaling receiver. - The device supports data exchange at up to 600 Mbps. - STMicroelectronics said the part is available for aerospace applications and can be used in space-related systems.

The details: - The RHFLVDS42 operates across a 2.3V to 3.6V supply range. - The device conforms to TIA/EIA-644 and Jedec low-voltage logic and power supply norms. - The receiver remains compatible with legacy CMOS designs. - The input common-mode voltage range extends from -4V to +5V. - The absolute maximum voltage rating is 4.8V. - The device is designed to improve link reliability and robustness against common-mode noise. - The part offers SEL-free operation at 122.6 MeV.cm²/mg. - The device is SET/SEU-free at 61.3 MeV.cm²/mg. - The RHFLVDS42 is stable per RHA QML-V at up to 300 krad TID (Si). - The receiver provides 8 kV ESD immunity. - STMicroelectronics manufactures the device in Rennes, France, using 130nm CMOS technology. - The technology has been used in space-related operations for over a decade. - The part meets EAR99 export administration regulations. - The device operates from -55°C to +125°C. - The standard package is a grounded-lid Flat-16 hermetic package. - The package uses a flow-through pinout that reduces crosstalk and helps save PCB space. - STMicroelectronics can also supply the RHFLVDS42 as bare die for size- and weight-sensitive applications. - More information is available in the company's announcement.

Between the lines: - The launch points to continued demand for space electronics that combine higher throughput with lower power and tougher radiation tolerance. - EAR99 status can simplify procurement for global customers, including organizations in the U.S. and Asia. - The bare-die option suggests STMicroelectronics is targeting both packaged systems and highly constrained designs where every gram and cubic millimeter matter.

What's next: - The RHFLVDS42 now enters the market as part of STMicroelectronics’ space-grade portfolio. - Aerospace teams will likely evaluate the receiver for new and existing platforms that need LVDS connectivity in harsh environments. - The company is positioning the part for supply-chain integration across global space and defense programs.
