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.
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 www.onsemi.com.
