ON Semiconductor Introduces the Industry's Fastest Emitter Coupled Logic -- ECL -- Crosspoint Switch for Telecom and Networking.

Business Editors/High-Tech Writers


The NBSG72A extends the GigaComm(TM) family

to include a crosspoint switch with two inputs

feeding two outputs that operates above 7 GigaHertz

Extending its industry leadership position in the high-speed Positively Referenced Emitter-Coupled Logic (PECL) market, ON Semiconductor (Nasdaq:ONNN) today introduced the NBSG72A -- a Silicon Germanium (SiGi) based, high bandwidth, fully differential crosspoint switch with output level select capabilities. The device is the newest member of the company's GigaComm(TM) family of high-performance logic ICs designed for the telecommunications, networking and automated test equipment industries.

Features and Benefits

Operating at speeds above 7 GigaHertz (GHz), the NBSG72A is the industry's fastest PECL crosspoint switch and ideal for high performance applications at OC-48 and OC-96 speeds of 2.5 gigabits per second (Gbps) and 5 Gbps respectively. Propagation delay is typically 140 pico seconds (ps) with rise times of 50 ps and fall times of 45 ps. The end result is an output signal that significantly improves timing margins over other solutions.

"The PECL performance of the NBSG72A is unparalleled in the industry and represents an entirely new functional class of devices for ON Semiconductor's GigaComm family(TM)," said Bill Schromm, ON Semiconductor vice president and director clock and data management products. "Competitive devices currently available are only available in Low Voltage Differential Signaling (LVDS) or Current-Mode Logic (CML)."

The NBSG72A features two inputs either of which can be routed directly, multiplexed to one or two outputs or fanned-out to both -- via the single-ended control pins that accept low voltage ECL (LVECL) or low voltage CMOS (LVCMOS) and transistor-transistor logic (TTL). The versatility of the device enables a myriad of application possibilities. In addition to routing reference clocks to different SERDES/Framers that utilize multi-rate devices, it can be implemented as a fan-out buffer, a serial digital video router, automatic protection switch or it can provide fast failure management by switching to alternative clock and data signals in a given system.

The Output Level Select feature of the NBSG72A offers programmability to the output signal peak-to-peak amplitude from 0 millivolts (mV) to 800mV in five discrete steps. This ensures the lowest possible electromagnetic interference, cross-talk and system noise. Like all members of the GigaComm(TM) family, this device features ON Semiconductor's AnyLevel(TM) technology. AnyLevel(TM) includes 50 ohms (U) input termination resistors and accepts all major signaling standards -- specifically Negative ECL (NECL), PECL, LVCMOS/LVTTL, CML or LVDS.

Packaging and Price

The NBSG72A is packaged in the 3mm by 3mm 16-pin Quad Flat No-lead (QFN) -- offering a minimum impact to board space andiIndustrial-grade temperature tolerance (-40(degree)C to +85(degree)C). It is priced at $11.13 per unit in 10,000 unit quantities.
