Capable of Data-Rates Above 12 Gigabits Per Second, the Enhanced GigaComm(TM) Devices Are Ideal for High-Performance Applications in OC-192 Networking and TelecommunicationsPHOENIX—(BUSINESS WIRE)—March 3, 2005— Applying decades of expertise in high-speed clock and data management to the networking and telecommunications markets, ON Semiconductor (Nasdaq: ONNN) today introduced the NB7L11M, NB7L14M, NB7L86M, NBSG16M, and NB7N017M -- Silicon Germanium (SiGe) based, high-bandwidth, fully differential clock distribution, clock driving, clock multiplexing, and clock pre-scaling ICs that support Current Mode Logic (CML) output. The devices are the newest members of the company's GigaComm(TM) family of high-performance clock and data management ICs designed for the telecommunications, networking, high-end computing and automated test equipment industries.
Features and Benefits
"As designers migrate from simple CMOS solutions to the performance range dominated by bipolar ICs, Current-Mode Logic is one of the most convenient protocols for high-speed interfacing and is quickly becoming the protocol of choice for emerging, high-bandwidth, networking applications," said Mike Radhanauth, ON Semiconductor director of marketing and business development for High Frequency Products.
The new GigaComm(TM) devices simplify initial conditions and connection termination with on-chip 50 ohm input and output termination. This allows for a point-to-point implementation expected of CMOS solutions, but uncommon in bipolar designs. Like Reduced Swing ECL (RSECL), the small 400 millivolt (mV) signal swing of CML results in reduced power consumption and rise/fall times. The irregularities that result from back reflection of signals later in the circuit -- which is common to high-frequency signaling -- are minimized by the on-chip termination.
Capable of data-rates above 12 Gigabits per second (Gbps) in some cases, these devices are ideal for high-performance applications in OC-192 applications. High-speed backplane interfacing is a breeze with propagation delay below 150 picoseconds (ps) and rise and fall times below 53 ps. Combined with the design flexibility inherent in CML, the performance capability of the NBSG16M results in an optimum solution for data transmission in networking applications.
