Abracon Corporation, a leading supplier of Frequency Control products, announces the release of AB-557-03, the world’s first family of crystal-less PCIe Clock Generators, now shipping in volume production. The AB-557-03 is a crystal-less, two-output PCI express clock generator meeting Gen1, Gen2 and Gen3 specifications. It uses patented silicon MEMS technology by Discera to provide PCIe compliant 100MHz differential output clocks with excellent jitter and stability over a wide range of supply voltages and temperatures.

“We at Abracon continue to expand our MEMS-based technology products into new applications where we can deliver innovative solutions along with system cost savings,” states Christopher Polley, President and CEO of Abracon Corporation. “We are committed to providing our customers with the latest emerging technology products that improve performance, while offering board space and unit cost savings.”

Design flexibility is another benefit of MEMS-based Clock Generator products. By eliminating the external quartz crystal, caps and tuning resistor, the AB-557-03 significantly enhances reliability and accelerates product development, while meeting stringent clock performance criteria for a variety of communications, storage, embedded and networking applications.

Jitter, temperature range, power consumption and a variety of available output formats are important design considerations for components designed for communications, storage and networking. Designers require the products that provide best in class capabilities in each category, such as those listed below. By eliminating the need for a crystal and other components, system board designers can further reduce cost and board size.

  • 65% Lower in jitter than IDT’s compatible part (0.15pS vs. 0.48pS) and 85% lower than the 1pS(max) PCIe Gen3 spec.
  • AB-557-03 Draws 25% lower power than IDT’s compatible device (60mA vs. 85mA).
  • The AB-557-03 supports multiple differential formats.

            - HCSL, LVPECL, or LVDS
    

  •      HCSL/LVPECL, HCSL/LVDS, LVPECL/LVDS

The comparable IDT part only supports HCSL.

  • The only PCIe clock generator in the industry that requires no external crystal and tuning caps.

The AB-557-03 is available for online ordering at http://www.DigiKey.com and http://www.Mouser.com in two different packages; a “drop-in’ replacement 16 pin TSSOP or a space-saving 14 pin QFP (77% less board space) ranging from $1.83 to $2.15 for 1K units.
