6/10/2003 - IDTTM (Integrated Device Technology, Inc.; Nasdaq: IDTI), a leading communications IC company, introduced its new QuadMux flow-control devices, the latest members of the IDT portfolio of flow-control management ICs. The new devices enable high-performance data-flow management by providing four independent ports on one side of the device, each with its own data memory block, and a single bus on the other, thereby enabling the convergence of four different data streams into a single data path. The new IDT QuadMux flow-control devices provide system architects with the first, fresh approach to both sequential and random manipulation of input and output data using a single, highly integrated device. This “superset” functionality is enabled using flexible and selectable port options.
The QuadMux flow-control devices can be configured to deliver multiplexing, de-multiplexing or broadcasting functionality with a total bandwidth of up to 16 Gbps, making them ideal for a range of communications applications, such as terabit routers and switch, base station routing systems, as well as data acquisition and imaging applications where data-stream convergence and parallel buffering of multiple data paths are required.
The new single-chip devices replace traditional and more costly methods of muxing multiple data streams at different data rates. For example, consider a line card within a chassis-based metro edge platform. The QuadMux architecture allows for the integration of data from multiple media interfaces by seamlessly rate matching the input data rate of each the media interfaces and the packet data rate of the converged data. Typically, these types of functions were accomplished with a multiplexer and considerable logic found in application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs) or a combination of standard logic and external memory. By using a QuadMux flow-control device and off-loading the data path management, a smaller, lower cost FPGA can be utilized, thereby reducing the cost of the system implementation.
“The QuadMux flow-control devices are standard, single-chip products designed to address the quality of service, packet prioritization and data bandwidth aggregation challenges faced by many of today’s communications system designers,” stated Michael Olsen, director of strategic marketing for IDT. “Designers have begun addressing these challenges by integrating data memory blocks into ASICs and FPGAs, but this can be costly and time consuming. Our high-performance QuadMux devices eliminate the need for this type of approach by delivering the performance and features required for today’s high-bandwidth applications. With our QuadMux flow-control devices, designers can lower their overall chip count and use a smaller and less expensive ASIC or FPGA. In short, we’ve leveraged our numerous years of experience in data-flow management to develop a class of devices that is unmatched in the industry.”
The read and write ports of each of the QuadMux device’s four data memory blocks can be configured independently, each with its own data rate of either single-data-rate (SDR) or double-data-rate (DDR) mode, clocking frequency, voltage and bus width. By providing five independent and discrete clock domains, the QuadMux flow-control devices enable multiple data streams to be processed or sent to various subsystems, each running independently, allowing multiple systems or subsystems to interoperate. The single common port of the device can operate as a x10, x20 or x40 bit bus, allowing flexibility in connecting to different subsystems. All of the ports can run up to 200 MHz, delivering data rates of up to 8 Gbps in SDR mode and 16 Gbps in DDR mode. Finally, the write and read ports of the QuadMux devices have the capability of operating their I/Os independently at 2.5-volt LVTTL, 1.5-volt HSTL or 1.8-volt eHSTL levels.
Pricing and Availability
Pricing for the new QuadMux flow-control devices ranges from $53.53 to $69.64 each in 10,000-piece quantities. All of the configurations listed below 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.
