DSC557-03/04/05
Multiple Output MEMS PCIe Gen1/2/3/4 Clock Generators
Features
General Description
• Complies with PCIe Gen1/2/3/4 Common Clock
Spec
The DSC557 series of high performance PCI Express
clock generators use
a proven silicon MEMS
technology to provide 100 MHz differential output
clocks with excellent jitter and stability over a wide
range of supply voltages and temperatures. By
eliminating the need for quartz or SAW technology,
MEMS oscillators significantly enhance reliability and
accelerate product development, while meeting
stringent clock performance criteria for a variety of
communications, storage, and networking applications.
• Integrated MEMS Resonator Eliminates the Need
for External 25 MHz Crystal
• Wide Temperature Range:
- Ext. Industrial: –40°C to +105°C
- Industrial: –40°C to +85°C
- Commercial: –20°C to +70°C
• 100 MHz HCSL/LVDS/LVCMOS Options
Available
The DSC557-03/04/05 have two, three, and four
100 MHz outputs, respectively. All have output
enable/disable features.
• Dedicated Output Enable (OE) Pins for Clock
Outputs
• Small Footprints:
The DSC557-03 is available in a space-saving 14-lead
VQFN package. The DSC557-04 and DSC557-05 are
available in a 20-lead VQFN.
- 14-Lead VQFN (DSC557-03, Two Outputs)
- 20-Lead VQFN (DSC557-04, Three Outputs;
DSC557-05, Four Outputs)
Additional LVDS and LVCMOS output formats are
available in addition to the default HCSL output format.
