DSC557-04
Crystal-lessв„ў Three Output PCIe Clock Generator
General Description Features The DSC557-04 is a Crystal-lessв„ў, three
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.
DSC557-04 has an Output Enable / Disable
feature allowing it to disable all outputs
when OE1 and OE2 are low. OE1 controls
CLK0 and OE2 controls CLK1/2. CLK1/2 are
synchronous PCIe clocks.
See the OE
function diagram for more detail.
