DSA557-03/04/05

Multiple Output MEMS PCIe Gen1/2/3/4 Clocks for Automotive

Features

General Description

• Automotive AEC-Q100 Qualified

The DSA557 series of high performance PCI Express

clock generators use

a proven silicon MEMS

• Complies with PCIe Gen1/2/3/4 Common Clock

Spec

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:

- Automotive Grade 2: –40°C to +105°C

- Automotive Grade 3: –40°C to +85°C

• 100 MHz HCSL/LVDS/LVCMOS Options

Available

The DSA557-03/04/05 have two, three, and four

100 MHz outputs, respectively. All have output

enable/disable features.

• Dedicated Output Pins for Clock Outputs

• Small Footprints:

- 14-Lead QFN (DSA557-03, Two Outputs)

The DSA557-03 is available in a space-saving 14-lead

QFN package. The DSA557-04 and DSA557-05 are

available in a 20-lead VQFN.

- 20-Lead VQFN (DSA557-04, Three Outputs;

DSA557-05, Four Outputs)

• Excellent Shock and Vibration Immunity

- Qualified to MIL-STD-883

Additional LVDS and LVCMOS output formats are

available in addition to the default HCSL output format.

• High Reliability

- 20x Better MTF than Quartz Oscillators

• Low Current Consumption: 30% Lower than

Competing Devices

• Supply Range of 2.25V to 3.63V

• Lead-Free and RoHS Compliant

Applications

• Automotive Infotainment

• Automotive ADAS

• Autonomous Driving

• In-Vehicle Network
