The steady increase of microprocessor performance has driven up operating frequencies in clock management products, causing a breakdown of conventional timing technology. To deal with higher frequency requirements, PMC-Sierra has launched a family of advanced Clock Management (CLK) products aimed at MIPS-based open architecture systems.

PMC-Sierra used its MIPS-based microprocessors and mixed-signal circuits to offer optimized clock management solutions for emerging MIPS-based platforms including set-top boxes, routers, printers, and advanced consumer applications.

The CLK family includes a low-skew buffer and two flexible clock generators. The low-skew buffers offer buffering of outputs for applications that require more copies of signals than are provided by the flexible clock generators. The flexible clock generators include spread spectrum technology and offers clocking for a wide range of applications by allowing the selection of multiple clock frequencies.

The spread spectrum technology lowers the level of electromagnetic interference (EMI) in a system, providing a significant tool in complying with radiation emission regulations like the FCC Class B.

The CM74CB218LSB-2x9 low-skew buffer and the CM5371 GEN-M7K and CM5391L GEN-M9K flexible clock generators are compatible with PMC-Sierra's MIPS-based microprocessors, the 200MHz to 900MHz RM7000 and RM5200 product families, and also the 1GHz RM9000 product family.

"Our new clock management products extend our company's commitment to our MIPS-based system customers," said Tom Riordan, VP and general manager of PMC-Sierra's Microprocessor Products Division.

To support environment-friendly electronic initiatives, PMC-Sierra is offering all CLK products in lead-free packaging.
