VSC8574RT PHY family launched, compatible with copper and fiber optic interfaces
Microchip Technology Inc. (NASDAQ: MCHP) has expanded its portfolio of radiation-tolerant Gigabit Ethernet PHYs, increasing development flexibility for aerospace and defense applications.
Microchip Technology Inc. today announced the availability of its VSC8574RT PHY family of radiation-tolerant Ethernet physical layer devices with expanded functionality.
The VSC8574RT PHY product supports Serial Gigabit Media Independent Interface (SGMII) and Quad Serial Gigabit Media-Independent Interface (QSGMII), which reduces the overall number of signal pins during the design process and secures the available space of the host device.
Space-related industrial applications require robust radiation-tolerant technologies that can withstand these harsh conditions, as extreme temperatures and electromagnetic phenomena in space can degrade system performance and disrupt normal operation.
The VSC8574RT Ethernet PHY product builds on Microchip’s extensive portfolio of commercial off-the-shelf (COTS) devices, allowing customers to begin initial application development with a COTS version and then upgrade to a radiation tolerant device in the final stage. It can be replaced, allowing for more efficient development.
In particular, the VSC8574RT PHY product has the potential to be utilized in a variety of applications because it is compatible with both copper and fiber interfaces.
Although copper is still primarily used, optical fiber interfaces are expected to be highlighted as a future material for space-related industrial applications that require data transmission speeds of 1 gigabit or more.
The VSC8574RT PHY product consists of quad ports supporting 10, 100, and 1000BASE-T Ethernet connections to ensure optimal speed and range depending on device requirements.
Additionally, this product is a highly reliable product with advanced features such as Synchronous Ethernet (SyncE) and IEEE 1588v2 (PTP: Precision Time Protocol), making it suitable for applications that require highly accurate timing and synchronization.
“The VSC8574RT PHY with advanced timing capabilities provides a connectivity solution for customers developing deterministic real-time applications,” said Bob Vampola, vice president of Microchip’s Aerospace and Defense business unit. “With increasing demand for Ethernet solutions to support space-related industrial applications, Microchip’s COTS-to-RT process device supports a growing number of these requirements with its multiple interfaces, including multiport, SGMII and fiber-optic interfaces.”
The VSC8574RT product has a single event latch-up (SEL) immunity of more than 78 MeV.cm²/mg and a robustness of 100Krad (kilorad) total ionizing dose (TID), which allows forIt can be widely used for applications ranging from low-Earth orbit (LEO) to deep space.
This new product launch expands Microchip’s portfolio of COTS-based Gigabit Ethernet PHY devices to include the VSC8574RT, VSC8541RT and VSC8540RT families.
