DSC557-03
Crystal-less Two Output PCIe Gen1/2/3 Clock Generator
General Description
The DSC557-03 is a crystal-less, two output
PCI express clock generator meeting Gen1,
Gen2, and Gen3 specifications. The clock
generator uses proven silicon MEMS
technology to provide 100MHz* differential
output clocks with excellent jitter and
stability over a wide range of supply
voltages and temperatures. By eliminating
the external quartz crystal, the DSSC557-03
significantly
enhances
reliability
and
accelerates product development, while
meeting stringent clock performance criteria
for a variety of communications, storage,
and networking applications.
DSC557-03 has an Output Enable / Disable
feature allowing it to disable the outputs
when OE is low. The device is available in
two
different
packages;
a
“drop-in”
replacement 16 pin TSSOP or a space
saving 14 pin QFN (77% less board space).
Additional output formats are also available
in any combination of LVPECL, LVDS, and
HCSL.
