DSC571-04

Crystal-less™ XAUI/SGMI/SRIO/PCIe Clock Generator

General Description

The DSC571-04 is a Crystal-less™ XAUI

clock generator with support for SGMI,

SRIO and PCI express 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.

DSC571-04 has input pins OE1 and OE2 for

Output Enable / Disable feature allowing it

to disable all outputs when OE(1:2) = 0.

See the OE function table 1 for more detail.

The device is available in a 20 pin QFN.

Output formats are available in any

combination of LVPECL, LVDS, HCSL and

LVCMOS

Features
