1/8/2003 - IDTTM (Integrated Device Technology, Inc.; Nasdaq: IDTI), a leading communications IC company, demonstrated its continued commitment to the communications market with the introduction of the industry’s first complete family of universal line interface units (ULIUs), including octal, quad, dual and single densities. These products enable designers to adopt a re-usable approach to line-card design by utilizing a single board that is configurable through software and may be easily re-scaled to suit different T1, E1 or J1 port densities and loop lengths. The IDT family of ULIU devices is an extension of the company’s existing short-haul line interface units (LIUs) and offer the ability to terminate both long haul and short haul T1, E1 or J1 connections.
Traditional long-haul applications apply to remote connection of business customers to the central office (CO), while short-haul applications typically apply to the interconnection of equipment within the same CO. Provision of a single, universal line termination, that can be configured for any protocol or loop length on a per port basis, allows T1, E1 or J1 equipment platforms to be used across multiple locations for connection of existing equipment to new packet switched networks.
The IDT ULIU devices target emerging line-card designs that are used in multi-service provisioning platforms, optical multiplexers, integrated multi-service access platforms, and broadband access equipment. While the IDT octal and quad ULIU devices support high-density equipment line-card applications, the dual and single ULIU products – in smaller packages and footprints – are designed for lower density line cards, access equipment and applications sensitive to single points of failure.
Industry-Leading Feature Set Addresses Customer Needs
The IDT ULIU family delivers the industry’s most advanced feature set, common across all densities. The per-channel software impedance matching and line build-out capability give designers the ability to create a single hardware platform with the configuration of each channel left to a software task executed prior to making a “live” connection. This ability is important as it enables customers to respond to the ever-changing market conditions and applications for communications equipment. A per-channel, programmable transmit pulse shaping feature allows further optimization of the pulse mask to address different line conditions.
To further ease the tasks of designers, all IDT ULIU devices integrate per-channel error counters, which keep track of bipolar violations, excessive zeroes and PRBS/QRSS pattern errors. The counters are sized such that they do not saturate for error rates of at least 10-2 with one second polling. In high-density applications, error counter integration conserves valuable pin and register resources within FPGAs or ASICs. By contrast, competing LIU devices provide a line coding error output for each channel that must be connected to the input pin on an external counter to maintain track of bipolar and code violations.
“The introduction of the IDT ULIU devices is a key step in our strategy to leverage our expertise in mixed-signal design to deliver the industry’s leading telecommunications components,” said Sean Fan, director of strategic marketing for the IDT telecommunications product division. “For example, unlike competing ‘point product’ solutions, our approach to line interface product development offers our customers a variety of key benefits, including common bill of materials, familiar features across different densities and single production software loads. In addition, the products provide a solid platform for next- generation transport devices, which we believe will include universal, integrated capabilities.”
The IDT ULIU devices ensure standards compliance by meeting or exceeding popular networking specifications by ANSI (T1.102, T1.403 and T1.408), ITU (I.431, CRT12/13, G.703, G.736, G.775, G.823), ETSI (300-166, 300-233) and AT&T (Pub 62411). The family also supports Hitless Protection Switching for 1+1 redundancy without relays and G.772 monitoring for in-service testing that meets ITU standards. Installation and testing issues are addressed by eight built-in, PRBS/QRSS pattern generators which, when combined with the internal loopback facilities, pattern detectors, error counters and remote diagnostics, enable many performance tests to be run “off-line,” without the need to bring test equipment on-site.
The IDT family of ULIU devices are currently sampling with production quantities available in Q1CY03. Volume pricing for the octal ULIU starts at $36.56 in 10,000-unit quantities. Volume pricing for the quad long-haul ULIUs starts at $21.95 in 10,000-unit quantities. Volume pricing for the dual ULIU starts at $13.36 in 10,000-unit quantities. Volume pricing for the single ULIU starts at $7.94 in 10,000-unit quantities. Development boards and software drivers for the IDT family of ULIU devices are available now.
