IDT® (Integrated Device Technology, Inc., introduces the latest member of its FemtoClocks family - the FemtoClock Next Generation (NG). This new family of clock synthesizers features very low phase-noise performance and significantly improved power-supply noise rejection, allowing for increased bandwidth when used with serial interfaces. The new FemtoClocks are fully customizable, stand-alone solutions that generate reference frequencies allowing them to replace crystal and SAW oscillators in high-performance applications. Additionally, the new FemtoClocks provide greater design flexibility in networking and telecommunications applications that utilize 10 Gigabit Ethernet, PCI Express, Fibre Channel and SONET interfaces by enabling multiple oscillators to be replaced with a single FemtoClock. The first device offered in this family, the 843N156-125, generates a 125 MHz single-ended output and a 156.25 MHz LVPECL output from a single 25 MHz crystal, replacing two crystal oscillators on the board with one device, providing application architects with increased design flexibility.
