6/10/2003 - IDTTM (Integrated Device Technology, Inc.; Nasdaq: IDTI), a leading communications IC company, unveiled its new multi-queue flow-control devices with double-data-rate (DDR) and single-data-rate (SDR) capabilities, representing the largest and fastest members of the company’s multi-queue family. IDT also introduced a new 2.5-volt addition to its multi-queue family. This announcement represents the first in a series of products included in the IDT portfolio of flow-control management ICs.
The IDT multi-queue flow-control ICs with DDR/SDR capabilities are ideal for applications where quality of service (QoS), data differentiation and parallel buffering of multiple data streams are required, including terabit routers, multi-service switching platforms and wireless base stations.
Joining the company’s existing 3.3-volt multi-queue family, the new single-chip multi-queue DDR/SDR devices include support for four queues with the ability to run either DDR or SDR at speeds up to 200 MHz in SDR mode and 400 Mbps in DDR mode, thereby enabling system matching. Each queue within the device has a common data input bus and common data output bus. Data can be read to and written from the device on every clock edge utilizing 100 percent bus utilization, even if the user is switching between queues. The devices include bus-matching features, allowing designers to configure read and write busses independently of each other either by bus width, speed, data rate or voltage. The new 2.5-volt multi-queue devices, also announced today, enable low-voltage designs and provide multi-queue features for up to 32 queues, at an industry-leading 200 MHz or 7 Gbps.
The new IDT multi-queue flow-control devices also provide designers with a new approach to both sequential and random access of data using a single, highly integrated device. This “superset” functionality is enabled using a range of device options. In addition to acting as a buffer, these new devices can be used to segregate and prioritize data at full-line rates through multiple queues. To support this function, designers previously utilized more expensive and cumbersome implementations.
“Traditionally, designers have addressed the challenges of data segregation and prioritization through the integration of multiple FIFOs, multiplexers and de-multiplexers, all requiring additional logic,” said Michael Olsen, director of strategic marketing for IDT. “Taking advantage of the new single-chip multi-queue flow-control devices with DDR and SDR capabilities can enable designers of communications systems to lessen design time by up to six weeks and reduce the size of the FPGA or ASIC by as much as 70 percent, depending on the application. The addition of the DDR/SDR devices, in tandem with the 2.5-volt multi-queue, underscores our commitment to delivering next-generation products with increased functionality and flexibility.”
The IDT Multi-Queue devices bring unique functionality to system architects. For example, Ethernet data coming into a system can be assigned one of several queues depending on the user-defined priority of the packet. Each queue can represent a different level of service. The local processor can utilize an algorithm to process high-priority packets first to ensure quality of service through the network. This prioritization can occur on the ingress or egress of a system to provide high-speed packet processing.
Pricing and Availability
The multi-queue DDR/SDR flow-control devices range in density from 1 Mbit to 5 Mbit and are configurable to x10, x20 and x40 bus widths. Pricing for the multi-queue DDR/SDR flow-control devices ranges from $42.50 to $58.50 each in 10,000-piece quantities. All of the configurations listed below are available now.

Pricing for the new 2.5-volt multi-queues ranges from $32.13 to $64.75 each in 10,000-piece quantities and are available now.
Flow-Control Management ICs
As a leading provider of innovative products for the communications market, IDT continues to evolve its distinctive competencies in the integration of advanced memory and logic architectures to create a new category of value-added semiconductor devices. The IDT flow-control management devices combine critical functions such as high-speed buffering, switching, multiplexing/de-multiplexing, domain transition and random and sequential access. These devices meet the special requirements of system architects who need to solve data-flow-control issues in their communications equipment designs. The IDT family of off-the-shelf devices replace traditional methods of muxing multiple data streams at different data rates — typically accomplished with a multiplexer, multiple application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), and external SRAM, DRAM or FIFOs.
IDT enhances the global network with semiconductor solutions for communications companies that lead innovation and drive convergence in voice, data and wireless networks. IDT is focused on enhancing system bandwidth with communications-specific products including network search engines, content inspection engines, flow-control management devices and the InterpriseTM family of integrated communications processors. The portfolio is also comprised of products optimized for communications applications, including telecom products, FIFOs, multi-ports, and clock management products. In addition, the product mix includes high-performance digital logic and high-speed SRAMs to meet the requirements of leading communications companies.
Headquartered in Santa Clara, Calif., the company employs approximately 3,100 people worldwide and has a wafer manufacturing facility in Oregon, and test and assembly facilities in the Philippines and Malaysia. IDT stock is traded on the Nasdaq Stock Market® under the symbol “IDTI.” The company is included in the S&P 1000, which is a combination of the S&P MidCap 400 and S&P SmallCap 600 Indices.
