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
pin
controls
two
banks
of
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.

ARM9200 interrupt problem
The code fixed in Flash is first moved to SDRAM for execution, but when an interrupt occurs, it seems to run back to Flash for execution. What is going on? How can I make the interrupt also run in SDR...
