Overview

The RHFLVDSR2D2K1 is a radiation-hardened dual LVDS transceiver designed for high-speed data transmission in harsh environments. It features two drivers and two receivers in a full-duplex configuration, supporting data rates up to 400Mbps while operating from a 3V to 3.6V supply. This component is housed in a hermetic 18-CFlatPack package and is specifically engineered to resist radiation-induced effects like SEL and SEU.

Why Choose This Part

This transceiver is guaranteed up to 300 krad(Si) Total Ionizing Dose (TID) and is SEL immune up to 135 MeV.cm2/mg. It includes a cold spare feature on all pins to ensure the part does not disturb the bus when powered off, and a fail-safe function that sets the receiver output to a known state during input faults.

Applications

Satellite Data Links
High-speed point-to-point communication between onboard computers and scientific instruments in Low Earth Orbit (LEO) or Geostationary Orbit (GEO).
Spacecraft Telemetry
Reliable transmission of critical spacecraft health and status data over differential pairs to minimize EMI in dense electronics bays.
Rad-Hard Sensor Interfaces
Interfacing high-resolution imaging sensors or radar modules to FPGA processing units in radiation-exposed environments.

Getting Started

Designers should follow ANSI TIA/EIA-644 standards for PCB layout, utilizing 100-ohm differential impedance controlled traces. Ensure the 18-CFlatPack footprint accounts for thermal dissipation and verify that the VDD supply remains within the 3.0V to 3.6V range for optimal performance. Given the rad-hard nature, consult the STMicroelectronics aerospace support documentation for specific derating and shielding guidelines.
