IDT Expands Flow-Control Management Product Portfolio

9/29/2004 - IDTTM (Integrated Device Technology, Inc.; Nasdaq: IDTI), a leading communications IC company, extended its leadership in the design and development of innovative data buffering solutions by announcing new members of its multi-queue family of flow-control management (FCM) ICs. Offering increased flexibility and functionality, the new devices help ease system design and reduce overall design costs. For example, the new IDT72P51769, a 4-Mbit multi-queue flow-control device, can access data from a single data bus and place the data into any of one to 128 queues, a 400 percent increase in queue partitioning over previous offerings. This allows the device to replace at least four devices previously required to perform the same functions. Also, data can be retrieved from any queue onto a single data bus, enabling the reordering and prioritization of information in data acquisition systems and image processing equipment, and ensuring quality of service (QoS) in processing networks. The IDT72P51769 achieves a low core voltage of 1.8 volts, resulting in a 25 percent decrease in overall power consumption. Using a x36 data bus, the IDT72P51769 offers a high data throughput of 7.2 Gigabits per second (Gbps).

“IDT is committed to developing best-in-class solutions that help designers solve data movement and access needs by providing innovative ways to enable policing, shaping and scheduling of data,” said Michael Olsen, product director for the IDT flow-control management division. “With this new device, IDT delivers a robust and flexible data buffering and queuing solution enabling these functions while reducing design time and cost in applications targeting the fast-growing data storage and image processing markets.”

The device’s new design offers unique features that make designing and implementing the part easier for both hardware and software engineers. The IDT72P51769 can be customized to the exact number of queues and individual queue sizes needed through parallel programming. The added flexibility that enables the device to handle partial packets simplifies the hardware design as well as the software needed to implement the design.

The IDT72P51769 also contains two new features called “mark and re-write” and “mark and re-read”, which enable the user to set markers on each queue. By over-writing data, mark and re-write offers more flexibility when passing data through a system, effectively dropping unwanted data so it doesn’t take up resources through the rest of the system. Mark and re-read allows data to be re-read once from a queue or multiple times if re-transmission of data is needed. The IDT72P51769 offers several value-added functions, such as user-selectable I/O on each port to simplify the interfacing of devices operating at different voltage levels, as well as bus matching, frequency matching, configurable queuing and programmable empty, partially empty, full and partially full flagging.

Pricing and Availability
IDT offers a comprehensive family of multi-queue devices, providing flexible interfaces, port-selectable bus widths, voltages and speeds. Accompanying the IDT72P51769 is a family of devices with densities of 0.5 Mbit, 1 Mbit, 2 Mbits and 4 Mbits and a maximum number of queues of 8, 32 and 128 offering optimized price points for different system needs. Pricing for the multi-queue flow-control family ranges from $36.95 to $69.95 each in high-volume OEM quantities. All are currently shipping in production quantities.

Flow-Control Management ICs
As a leading provider of innovative products for the communications market, IDT continues evolving its distinctive competencies in integrating advanced memory and logic architectures, creating a new category of value-added semiconductor solutions called flow-control management (FCM) devices. FCM products provide access and/or queuing for data streams between subsystems and explicitly assist with additional functions, such as policing, shaping, scheduling, or directing the data. FCM devices have extensive impact in communications subsystem designs and also provide benefits in medical, video and data acquisition applications. The devices replace traditional methods of managing the flow of data within a system — previously accomplished with multiple ASICs, FPGAs and external SRAM, DRAM or FIFOs. The IDT FCM portfolio consists of devices that execute packet exchanging, queuing and multiplexing functions.
