Sipex Announces World's First 3V Only, 8 Channel Multiprotocol Transceiver
The SP3508 Supports Eight Different Protocols with the Fastest Data Rates in the Industry
(Milpitas, CA - August 26, 2003) - Sipex Corporation (NASDAQ:SIPX), a leading provider of high performance, analog integrated circuits (ICs), today introduced the SP3508, the world's only 3V, 8 channel, one-chip multiprotocol transceiver. Capable of data rates up to 20Mbps, the SP3508 enables faster data communications between nodes in Wide Area Network (WAN) applications such as routers, remote access and file servers.
By providing a single-chip integrated solution, the SP3508 offers a number of substantial benefits over other products in the market. Through its operating power supply of 3V, its TTL I/O lines are conditioned to LVTTL signal levels and thus eliminate the need for costly external logic translators. The device incorporates a patented intelligent charge pump to generate the typical voltages of +/-5.5V to support the output voltage swings required for serial communications standards. To configure the device for V.35 and V.11 protocols, the product features integrated termination resistors that are software configurable. The SP3508 also complies with the popular NET1/NET2 standards as well as the more stringent TBR2 standard.
The SP3508 supports eight popular serial interface protocols and offers true programmable DTE/DCE capability for all eight drivers and receivers through their individual tri-state control pins. Any of the supported protocols can be selected by applying a 3 bit code to the selection pins.
"As a designer and manufacturer of state-of-the-art military, government and commercial communications systems, the use of the Sipex multi-protocol SP508 and SP509 single-chip transceivers is paramount. These single-chip solutions offer a compact, versatile, robust design for high-speed multi-protocol data transmission," said Ron Di Christofaro, L-3 Communications Systems engineering. "The SP3508 extends the versatility of Sipex's single-chip solutions by providing a 3 volt I/O port for ease of interfacing to the low voltage / low power FPGA's, DSP's and logic families."
"The SP3508 appeals to designers since it significantly reduces component count, required board space and power consumption," said Kevin Plouse, senior vice president of marketing and business development for Sipex. "With 8 data channels, 20Mbps data rate and an integrated charge pump, this solution provides system designers a distinct improvement over existing dual-chip and slower single-chip alternatives."
