ON Semiconductor expands portfolio of differential amplifiers for broadband applications

Aug. 1, 2001--ON Semiconductor Corp. has introduced a new series of differential amplifiers beneficial to the design of SONET/SDH, Gigabit Ethernet, Fibre Channel and Infiniband reference clock-oscillator modules.

ON Semiconductor Corp. (Nasdaq: ONNN) has introduced a new series of differential amplifiers beneficial to the design of SONET/SDH, Gigabit Ethernet, Fibre Channel and Infiniband reference clock-oscillator modules, as well as backplane and fiber-optic module applications requiring improved input sensitivity. These devices address engineering needs for high gain, buffered feedback and output enabling requirements.

Capable of operating at speeds greater than 3 Gigahertz (GHz), these 3.3- to 5-volt devices are designed for OC-3, OC-12 and OC-48 applications. An impressive voltage gain of greater than 200 allows for a significantly reduced input signal swing. The inherent jitter, measuring less than 1 picosecond (ps), is appealingly low for challenging telecom applications.

Both the MC100EP16VB and the MC100EP16VC incorporate high gain and the buffered feedback necessary to crystal oscillator applications. With typical edge speeds of 150 ps, both provide crisp clock edges. The inclusion of a reference voltage output in each device facilitates their usage in ac-coupled inputs. As an extra feature, the MC100EP16VC adds a synchronous-enable control that allows the output to be turned on and off with a high degree of reliability.

The MC10/100EP16A are straight-forward, fully differential amplifiers. Their high-gain capabilities and fast edge rates (110 ps) make them attractive for pulse and limiting amplifier applications.

In addition to delivering a space-saving 8-pin configuration, ON Semiconductor has provided design engineers with the added flexibility of choosing the packaging most appropriate to their needs. Each device is available in standard SOIC-8, compact TSSOP and die form. Pricing for each of the three devices is $2.76 for 10,000 units.

While ideal for implementation in reference clock oscillator modules designed for SONET/SDH, Gigabit Ethernet, Fibre Channel and Infiniband, these new clock generation devices are equally suited for use in networking equipment, Automatic Test Equipment (ATE), medical imaging and measurement equipment, and high-performance computing.
