DSC556-03
Crystal-lessTM Two Output PCIe Gen1 Clock Generator
General Description
The DSC556-03 is a crystal-less™, two
output, Gen.1 PCI express clock generator.
The device implements Discera’s 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 DSC556-03 significantly enhances
reliability and accelerates product
development, while meeting stringent clock
performance criteria for a variety of
Embedded, Industrial, storage, and
networking applications.
DSC556-03 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).
