Expanding its high performance portfolio of clock management solutions, ON Semiconductor (Nasdaq: ONNN) has introduced three new 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, the new devices are ideal for use in telecommunications, networking and automated test equipment (ATE). “With a portfolio that encompasses clock synthesis, clock generation and clock distribution, ON Semiconductor is quickly emerging as a key player in the market space,” said Bill Hall, ON Semiconductor senior vice president and general manager of the Standard Products Group. “Our competitively priced timing solutions deliver the industry’s highest performance and best quality. The company’s reputation for solid delivery and superior customer service serves to further strengthen the confidence of our customers. 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 Devices The NB3N551 clock fanout buffer operates at up to 180 megahertz (MHz), and at VCC of 3.3 volts (V) or 5.0 V. The device provides an upgrade to the industry standard ICS551, with improved maximum output skew of 160 picoseconds (ps) versus 250 ps for existing products. Packaged in a lead free (Pb-free) SOIC-8 package or a space-saving (2.0 mm x 2.0 mm) DFN-8 package, the NB3N551 is budgetary priced at $0.80 USD per unit in 2,500 unit quantities. The NB3L553 clock fanout buffer operates at up to 200 MHz with only 35 ps typical skew between outputs and is pin compatible to the industry standard ICS553. The device operates at VCC of 2.5 V, 3.3 V or 5.0 V. It is packaged in the Pb-free SOIC-8 and budgetary priced at $0.87 USD per unit in 2,500 unit quantities. Operating at up to 140 MHz 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 3.0 V to 3.6 V and is ideal for PCI/PCI-X applications. Packaged in a 4.4 mm x 3.0 mm Pb-free 8-pin TSSOP, the NB3N2304NZ is budgetary priced at $0.87 USD per unit in 2,500 unit quantities. * Input/Output Clock Frequency up to 140 MHz * Low Skew Outputs (100 ps) * Operating Range: VDD = 3.0 V to 3.6 V * Packaged in 8pin TSSOP, 4.4 mm x 3 mm * Industrial Temperature Range
