LEOLVDSRDPT-D
Overview
The LEOLVDSRDPT-D is a radiation-hardened 1/1 LVDS transceiver specifically designed for Low Earth Orbit (LEO) satellite applications. It provides full-duplex communication at data rates up to 400Mbps while operating from a 3V to 3.6V supply. This component is optimized for harsh environments with a total ionizing dose (TID) rating of 50 krad (Si) and is SEL-free up to 62.5 MeV.cm2/mg.
Why Choose This Part
This transceiver features a cold spare function on all pins to prevent leakage when the device is unpowered, and a fail-safe mechanism to ensure predictable output states. It is built with a whisker-free NiPdAu lead finish and gold wires for high reliability in vacuum environments, maintaining a low 4mA maximum standby current.
Applications
Key Specifications
Getting Started
Designers should follow STMicroelectronics LEO-series design guidelines, ensuring proper differential impedance matching for the 400Mbps LVDS lines. Integration typically involves validating the fail-safe and cold spare behavior within the system power-sequencing plan for the satellite's communication backplane.
