Peregrine Launches RS422 Rad-Hard Transmitter/Receiver Duo

San Diego -- Peregrine Semiconductor today announced the availability of the PE926C31 RS422 rad-hard transmitter and the PE926C32 RS422 rad-hard receiver devices for space applications. According to Peregrine, the chipset -- developed on the company's proprietary UltraCMOS silicon-on-sapphire technology -- is the lowest power rad-hard RS-422 standard interface offering on the market. The devices feature single event upset (SEU) immunity of <10^-10 errors/bit-day, high-speed operation at <10 nS, and low-power at <150 mA (unloaded).

"UltraCMOS technology continues to prove that superior products don't need a superior pricetag or an exotic process," stated Jim Cable, CEO of Peregrine Semiconductor. "The most stringent quality assurance demands come from engineers designing for space. By designing, manufacturing, and bringing to market rad-hard versions of devices that meet a standard interface protocol, Peregrine demonstrates the most exceptional features of the UltraCMOS process to the benefit of our customers."

The PE926C31/32 devices operate at 3.3 V with a total dose tolerance guaranteed to 300 KRads (Si), which makes them ideal for satellite applications.

Evaluation kits support development with the devices, which are packaged in the 16-lead ceramic flat pack (CFP), and UltraCMOS technology tutorials are available from Peregrine. The chipset is in production now.
