The industry leader in SRAMs, announced that ZTE Corporation, a leading global provider of telecommunications equipment and network solutions, has selected Cypress’s QDR™II (Quad Data Rate™) SRAM devices for the new ZXCME 9500 series of Ethernet switches.

Cypress Semiconductor Corp. (Nasdaq: CY), the industry leader in SRAMs, announced that ZTE Corporation, a leading global provider of telecommunications equipment and network solutions, has selected Cypress’s QDR™II (Quad Data Rate™) SRAM devices for the new ZXCME 9500 series of Ethernet switches. Cypress’s 65-nm 72-Mbit QDRII SRAMs deliver the market’s fastest available clock speed of up to 550 MHz, feature the market’s broadest portfolio of device options, and are supported by the industry’s most extensive network of reference designs.

In addition to Ethernet switches, the 72-MBit devices are ideal for Internet core and edge routers, 3G base stations, secure routers and also enhance the performance of medical imaging and military signal processing systems. The devices are pin compatible with 90-nm SRAMs, enabling networking customers to increase performance and port density while maintaining the same board layout.

“The excellent speed and low latency of Cypress’s SRAMs are instrumental in the outstanding performance that the ZXCME 9500 series offers our customers,” said Li Hongqi, product development manager at ZTE. “Cypress has a well established history as a leader in SRAM technology, making them a supplier we trust for multiple products.”

“When leading networking companies such as ZTE choose our SRAMs, we know that we are providing winning products,” said David Kranzler, Vice President of Sync and Timing Products at Cypress. “Cypress was first to market with 65-nm SRAM devices, proof of our commitment to supporting the SRAM market long-term and to building on our leadership position.”

The ZXCME 9500 series Metro Ethernet products offer carrier-class bearing and transport of multiple services, mainly positioned at the core/aggregation layer of a Metro Network. The series features an advanced distributed and modular architecture and design, and uses large-capacity switching fabric. With a maximum backplane bandwidth of 2.52 Tbps, the ZXCME 9500 series products offer fast protection switchover and redundant backup of key modules and power supply to provide a 100-percent reliable network operating platform.

Compared with their 90-nm predecessors, the 65-nm QDR SRAMs reduce operating power by 40 percent. The QDRII devices feature an On-Die Termination (ODT) option, which improves signal integrity, reduces system cost, and saves board space by eliminating external termination resistors. The 65-nm devices use a Phase Locked Loop (PLL) instead of a Delay Locked Loop (DLL), which enables a 35 percent wider data valid window, thereby reducing system development time and expense for the customer.
