Keysight Technologies N4974A PRBS Generator 44 Gb/s Data Sheet Description The Keysight Technologies, Inc. N4974A PRBS generator 44 Gb/s is a self-contained pattern generator capable of operating at either a single fixed-frequency bit rate using the internal oscillator or operat- ing over a wider frequency range when used with an external half-rate clock source. The N4974A PRBS generator 44 Gb/s operates from 22 to 44 Gb/s when used with an external clock or at 39.81312 Gb/s when used with the internal oscillator. The generator is also avail- able with two more internal oscillator choices, operating at either 25.78125 or 28.0 Gb/s. The N4974A PRBS generator 44 Gb/s source is based on custom ASICs, allowing a high degree of integration. The low parts count in the signal path minimizes the degradation of the low phase noise oscillator, providing an extremely clean eye pattern. Utilizing the internal oscillator, the generator achieves world class performance of 500 fs rms jitter, with a 500 mV output amplitude and 8 ps rise time. Application The N4974A PRBS generator 44 Gb/s source is designed to be used as the source for testing ultra-high speed communications com- ponents such as those used in OC 768/STM 256 applications. The 40G PRBS source is a perfect companion to a digital communication analyzer in a stimulus response measurement for 40 Gb/s compo- nents such as driver amplifiers, transimpedance amplifiers, optical modulators, and DEMUX. Other applications include backplane signal integrity testing, and cable testing. Features
