Expanding its high performance portfolio of clock management solutions, ON Semiconductor has introduced three highly accurate, low skew, 1:4 clock fanout buffers with CMOS outputs. The NB3N551, NB3L553, and NB3N2304NZ significantly outperform competitive devices. Used to create multiple copies of clocks at full system frequencies, these devices are suitable for use in telecommunications, networking and automated test equipment (ATE).

During the coming year, we plan to introduce additional high performance clock solutions that target the demanding technological needs of the telecom and data communications marketplace."

The NB3N551 clock fanout buffer operates at up to 180MHz, and at VCC of 3.3V or 5V. The device provides an upgrade to the industry standard ICS551, with improved maximum output skew of 160ps versus 250ps for existing products. Packaged in a lead free (Pb-free) SOIC-8 package or a space-saving (2-by-2mm) DFN-8 package, the NB3N551 is budgetary priced at Rs.36.26 (80 cents) per unit in 2,500 unit quantities.

The NB3L553 clock fanout buffer operates at up to 200MHz with only 35ps typical skew between outputs and is pin compatible to the industry standard ICS553. The device operates at VCC of 2.5V, 3.3V or 5V. It is packaged in the Pb-free SOIC-8 and budgetary priced at Rs.39.43 (87 cents) per unit in 2,500 unit quantities.

Operating at up to 140MHz with a maximum skew of 100ps, the NB3N2304NZ clock fanout buffer is a pin compatible second source to the industry standard ICS2304NZ. This device operates at VCC of 3V to 3.6V and is suitable for PCI/PCI-X applications. Packaged in a 4.4-by-3mm Pb-free 8-pin TSSOP, the NB3N2304NZ is budgetary priced at Rs.39.43 (87 cents) per unit in 2,500 unit quantities.
