NETWORKING: ON Semi intros Programmable Clock Multiplier for consumer networking apps


Phoenix, Az. – ON Semiconductor has just introduced its NB3N3020 high precision, low phase noise, programmable clock multiplier for which it claims best-in-class jitter performance.

The device generates an LVPECL clock, as well as LVCMOS clock on the same device which enables the NB3N3020 to be used in a wide range of applications including networking, consumer electronics and computing applications.

It has three tri-level LVCMOS single ended select pins that set one of 26 possible clock frequencies allowing flexibility for the designer to meet requirements and replace many clocks in different systems with a single custom-tailored device.

The programmable clock multiplier has a wide output frequency range from 8 Megahertz (MHz) to 210 MHz. It takes a 5.0-27 MHz fundamental mode parallel resonant crystal or a 2.0-210 MHz LVCMOS single ended clock source and generates a differential LVPECL output and a single ended LVCMOS output at a selectable clock output frequency which is a multiple of the input clock frequency.

The LVCMOS output enable (OE) tri-states clock outputs when low, allowing system designers to dynamically control the presence of clock timing in their systems. The device has excellent jitter performance with period jitter of 5 picoseconds (ps) resulting in more system timing margin for board designers, higher frequency designs and higher reliability.

To find out more on the applications of NB3N3020 in set top box, digital TV, home gateways, networking and various consumer products, you can view the course online at Techonline.

The NB3N3020 is available in a 5.0 mm x 4.4 mm TSSOP-16 package with a budgetary price of $3.50. To learn more, go to
