DSC558-05

Crystal-less™ Four Output PCIe Clock Generator

General Description

The DSC558-05 is a Crystal-less™, four

output PCI express clock generator meeting

Gen1, Gen2, and Gen3 specifications, with

an additional 60MHz general purpose clock.

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.

DSC558-05 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 table 1 for

more detail. The device is available in a 20

pin QFN. Additional output formats are in

any combination of LVCMOS, LVPECL, LVDS,

and HCSL.
