PMC-Sierra Optimizes CM5470 System Clock Generator for MIPs Platforms

7/7/2004 - PMC-Sierra, Inc. (Nasdaq:PMCS) introduced the CM5470 system clock generator, the latest addition to its family of Advanced Clock Management (CLK(TM)) products. The highly integrated CM5470 device, designed for direct compatibility with PMC-Sierra's 200 to 900 MHz RM7000(TM) and RM5200(TM) MIPS-based(TM) microprocessor product families, is optimized for MIPS-based printer and consumer applications. The CM5470 device provides a single-chip clocking solution to drive all of the components commonly implemented alongside MIPS(R) processors, including CPU clocks, USB, LAN, PCI, and RAM clocks. PMC-Sierra's industry-leading system clock generator will enable OEMs to accelerate their design process and time-to-market.

"PMC-Sierra has worked closely with lead customers in defining our first system clock generator for the printer and consumer markets. Our firsthand system-level knowledge and experience in MIPS-based platforms, together with customer input, have lead to the development of optimal system-level clocking solutions," said Aaron Gilroy, marketing manager, Microprocessor Products Division at PMC-Sierra. "We have leveraged our mixed-signal design expertise and proven clock management technology to provide feature-rich and reliable advanced clock management products for MIPS-based equipment."

System Solution for MIPS-Based Printer and Consumer Platforms
The CM5470 device provides tailored combinations of frequencies and I/O types required in MIPS-based printer and consumer platforms. The CM5470 device provides CPU, RAM, PCI, USB, and LAN reference clocks. In addition, the device includes optional spread spectrum modulation to aid designers in meeting system radiation requirements. PMC-Sierra has evaluation platforms and reference boards to ensure testing and compatibility of PMC-Sierra CLK solutions within a system environment.

"PMC-Sierra offers best-in-class applications support for our MIPS-based processor and clock management product families. As the printer and consumer markets continue to grow in Asia, time-to-market will be key for our customers," said Tom Sun, vice president of Asia Pacific Operations at PMC-Sierra. "The collaboration of our MIPS-based processor and clock management teams will assist our customers in ensuring timely project development and release."

The System Clock Generator provides multiple frequencies and I/O types to address targeted MIPS-based applications. The Flexible Clock Generators deliver multiple copies of an identical frequency and offer clocking for a broad set of applications. Both generator categories provide integrated spread spectrum modulation for EMI reduction. The Low-Skew Buffer enables buffering of outputs for applications that require more copies of signals than are provided by the generator devices.

The CLK products are compatible with PMC-Sierra's MIPS-based microprocessors, the 250 to 900 MHz RM7000 and RM5200 product families, as well as the 1GHz RM9000(TM) product family. For more information, visit

Pricing, Availability, Packaging and Customer Support
PMC-Sierra's CM5470 device is priced at $1.75 in 10KU and is currently sampling. Lead-free packaging is available for all CLK products to support the "Green" electronic initiatives. The CM5470 is available in a 56-pin TSSOP and 6.1x14mm package. The device is low power, 0.18 CMOS and rated for commercial temperature range operation (0 to +70 degrees Celsius).
