DSC557-05

Crystal-less™ Four Output PCIe Clock Generator

General Description

The DSC557-05 is a Crystal-less™, four

output PCI express clock generator meeting

Gen1, Gen2, and Gen3 specifications. The

clock generator uses proven silicon MEMS

technology to provide excellent jitter and

stability over a wide range of supply

voltages and temperatures. By eliminating

the external quartz crystal, MEMS clock

generators significantly enhance reliability

and accelerate product development, while

meeting stringent clock performance criteria

for a variety of communications, storage,

and networking applications.

DSC557-05 has an Output Enable / Disable

feature allowing it to disable all outputs

when OE1 and OE2 are low. Each output

enable

controls

two

banks

synchronous PCIe clocks.

See the OE

function diagram for more detail.

The

device is available in a 20 pin QFN.

Additional output formats are in any

combination of LVPECL, LVDS, and HCSL.
