65-nm QDR II+ SRAMs offer operating speed of 550 MHz
ZTE, a provider of telecommunications equipment and network offerings, has selected Cypress Semiconductor’s QDRII+ (Quad Data Rate) SRAM devices for its new ZXCME 9500 series of Ethernet switches.
Cypress said that its 65-nm 72-Mbit QDRII+ SRAMs delivers a clock speed of up to 550 MHz, and features a range of device options.
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 company said ZXCME 9500 series metro Ethernet products offer carrier-class bearing and transport of multiple services, and features distributed and modular architecture, design, and uses large-capacity switching fabric.
In addition, ZXCME 9500 series products with a maximum bandwidth of 2.52 Tbps offer protection switchover and redundant backup of key modules and power supply.
ZTE product development manager Li Hongqi said the speed and low latency of Cypress’s SRAMs are instrumental in the outstanding performance that the ZXCME 9500 series offers its customers.
