DSA400

Configurable Four Output, Low Jitter Clock Generator for Automotive

Features

General Description

• AEC-Q100 Automotive Qualified

• Low RMS Phase Jitter: <1 ps (typ.)

The DSA400 is a four output clock generator. It utilizes

proven PureSilicon™ MEMS technology to provide

excellent jitter and stability while incorporating

additional device functionality.

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

Spec

The nominal frequencies of the outputs can be identical

or independently derived from common PLLs.

• High Stability: ±25 ppm, ±50 ppm

• Wide Temperature Range:

The four output DSA400 MEMS oscillators are

excellent choices for use as clock references in

automotive applications in which small size, low power

consumption, and long-term reliability are paramount.

The DSA400 is AEC-Q100 qualified.

- Automotive Grade 2: –40°C to +105°C

- Automotive Grade 3: –40°C to +85°C

• High Supply Noise Rejection: –50 dBc

• Four Format-Configurable Outputs:

- LVPECL, LVDS, HCSL, LVCMOS

• Available Pin-Selectable Frequency Table

- 1 Pin per Bank for 2 Frequency Sets

• Wide Frequency Range:

Each output may be configured independently to

support a single-ended LVCMOS interface or a

differential interface. Differential options include

LVPECL, LVDS, or HCSL.

- 2.3 MHz – 460 MHz

The DSA400 provides two independent select lines for

choosing between two sets of pre-configured

frequencies per bank. It also has two OE pins to allow

for enabling and disabling outputs.

• 20-Pin QFN Footprint (5.0 mm x 3.2 mm)

• Excellent Shock and Vibration Immunity

• High Reliability

The DSA400 is packaged in a 20-pin QFN (5 mm x

3.2 mm) and is available in extended commercial and

industrial temperature grades.

- 20x better MTF than quartz-based devices

• Wide Supply Range of 2.25V to 3.6V

• Lead Free and RoHS-Compliant

The DSA400 is a highly configurable device and is

factory programmed to meet the customer’s needs.

Microchip’s ClockWorks Configurator must be used to

choose the necessary options, create the final part

number, data sheet, and order samples.

Applications

• Automotive Infotainment

• Automotive ADAS

• Autonomous Driving

• In-Vehicle Network
