IDT Releases New SuperJET J1/E1/T1 Transceiver Family

4/29/2003 - IDTTM (Integrated Device Technology, Inc.; Nasdaq: IDTI), a leading communications IC company, announced its new SuperJETTM family of J1/E1/T1 transceivers, including the industry’s first monolithic octal density device, to address next-generation universal line-card designs in communications applications. The SuperJET transceivers, which integrate and expand upon the IDT universal line interface unit (ULIU) and framer functionality, deliver industry-leading configuration flexibility, jitter performance and signaling support across the family’s octal, quad, dual and single densities. This family is the first of its kind to address the universal line-card market by enabling independent, per-channel programming of J1, E1 or T1 line impedance matching, frame formatting, line code and line build out. Each device in the SuperJET family utilizes a common architecture, feature set and register map to provide an easy migration path between densities and to allow designers to reuse existing software. Universal line-card designs using the IDT SuperJET products give system manufacturers the power to leverage a single design and bill of materials (BOM) to save cost, reduce line-card variants and accelerate time to market.

“Our monolithic octal transceiver is an industry first, offering twice the density of alternative solutions and programming flexibility that extends throughout the SuperJET family,” stated Sean Fan, director of strategic marketing for the IDT telecommunications product division. “These products not only satisfy the traditional requirements of J1, E1 and T1 WAN interfaces, but also address new challenges in communications line-card design, such as higher density, multiple protocols and network timing.”

The SuperJET family meets and exceeds ITU, ETSI and AT&T jitter specifications and can simplify system design and eliminate external components with integrated jitter attenuators (JAT) in both the transmit and receive directions of each channel. The dual JATs allow the SuperJET transceivers to simultaneously reduce jitter from both the line and system clocks, which may have jitter and gaps due to de-multiplexing. This capability is especially useful in multi-service applications where loop re-timing is often required between ATM or IP networks and J1/E1/T1 spans.

To enable complete support for SS7 and V5.x standards without requiring external logic or HDLC resources, the SuperJET transceivers provide three HDLC controllers per channel, each with 128-byte FIFO buffers. Any HDLC controller can be configured in HDLC or SS7 mode and offers V5.2 link ID, auto-FISU transmission and automatic processing of FISU and LSSU packets, effectively reducing the microprocessor load. In addition, the SuperJET family supports SLC-96 framing and overhead processing, including overhead buffers and de-bouncing, required by GR-303. The SuperJET transceivers operate in any mode using a single, flexible reference clock at a multiple of 1.544 MHz or 2.048 MHz, thereby simplifying line-card design.

The IDT SuperJET devices target J1/E1/T1 interfaces in access concentrators, wireless base stations, integrated multi-service access platforms, synchronization networks and broadband access equipment. The octal and quad devices are ideal for V5.2 and GR-303 interfaces because of their density, HDLC resources and SLC-96 support. The dual and single devices – in smaller packages and footprints – are designed for lower-density line cards, access equipment and applications sensitive to single points of failure. They are also especially well suited for network timing interfaces in SONET, SDH and OTN equipment.

Development boards, board software, C-based software drivers and manuals are available for each SuperJET device. This family of SuperJET devices can also be combined with the existing TSI switches and WAN PLL devices from IDT to provide a complete line-card solution.
