Rugged, radiation-hardened LVDS line drivers for space applications introduced by 3D Plus

MC KINNEY, Texas, 4 Feb. 2011. 3D Plus USA Inc. in McKinney, Texas, is introducing a line of radiation-tolerant low-voltage differential signaling (LVDS) line drivers and receivers for high-speed point-to-point interface in space applications such as deep space missions, earth observations, navigation, launchers, and manned space vehicles.

The rad-hard LVDS line drivers, which embed eight or 16 LVDS channels in one miniaturized package, are designed to withstand harsh thermal and mechanical environments. The radiation-hardened devices resist total-dose radiation of more than 50 kilorads, resist single-event latchup of more than 80 Mev.cm2/mg, and are immune to single-event upsets.

The devices are available in a variety of temperature ranges and with one power supply of 3.3 or 5 volts. the devices are offered with standard SOP footprint for high resistance SMT assembly. LVDS is an electrical signaling system that can run at high speeds over inexpensive twisted-pair copper cables.

Key features include 400 megasample-per-second (200 MHz) switching rates; low power dissipation; compatible with IEEE 1596.3 SCI LVDS standard; conforms to ANSI/TIA/EIA-644 LVDS standard; ; and last for 15 to 18 years in space.
