The SCAN921025H serializer and SCAN921226H deserializer from National Semiconductor Corp. deliver up to 10 bits of digital data at 20MHz to 80MHz over a single point-to-point differential interconnect in backplanes or cable.

An addition to the company's portfolio of LVDS (low voltage differential signaling) products, this SerDes (serializer/deserializer) chipset operates in harsh environments up to 125C.

Harsh automotive and industrial environments require a SerDes chipset that can withstand high temperatures and noise, and includes testability for continuous, reliable operation, said National. To enable system testing in the environments with high temperatures, the company integrated BIST (built-in self-test) and JTAG into its two new devices.

"Features such as extended temperature and JTAG further expand our high-speed analog interface market presence in the industrial and automotive segments," said Jeff Waters, product line director for the Communications Interface division at National. "Automotive and industrial data transfer and display applications demand robust products, and National will continue to meet those needs through innovations in ruggedness and testability."

The high-speed LVDS SCAN921025H serializer transforms a 10bit wide parallel LVCMOS/LVTTL data bus into a single high speed serial data stream with embedded clock. The serializer receives the LVDS serial data stream and converts it back into a 10bit wide parallel data bus plus clock. According to the press release, this single serial-data path makes PCB design easier, and the reduced cable, PCB trace count and connector size significantly reduces cost.

Both the SCAN921025H and SCAN921226H operate between 20MHz and 80MHz, delivering full data payloads from 200Mbps to 800Mbps. They are priced at $5.90 each in 1,000-unit quantities, and are housed in the FBGA-49 package.
