High performance clock generation ICs

6 February 2008 Telecoms, Datacoms, Wireless, IoT

ON Semiconductor has expanded its PureEdge high performance clock generation family with the introduction of the NB3N3002 and NB3N5573. Both devices are 3,3 V clock generators that create selectable host clock signal Levels (HCSL) and sub-picosecond jitter quality clocks at 25 MHz, 100 MHz, 125 MHz and 200 MHz. They are aimed at PCI Express, Gigabit Ethernet and FBDIMM applications. The NB3N3002 generates one differential HCSL output clock, while the NB3N5573 delivers dual output, and both provide phase noise of -130 dB relative to the carrier per Hertz (dBc/Hz) at 100 kHz offset from the carrier frequency. Employing advanced CMOS technology, the devices deliver phase noise comparable to expensive surface acoustic wave (SAW) crystal oscillators. Both devices are offered in a 5,0 mm x 4,4 mm lead free TSSOP-16 package.
