DSA1101/21/05/25

Low-Jitter Precision CMOS Oscillator for Automotive

General Description

Features

• Automotive AEC-Q100 Qualified

• Two Rise/Fall Time Options for EMI Reduction

• Low RMS Phase Jitter: <1 ps (typ.)

• High Stability: ±20 ppm, ±25 ppm, ±50 ppm

• Wide Temperature Range:

The DSA1101 and DSA1121 series of high

performance oscillators utilize a proven silicon MEMS

technology to provide 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.

- Automotive Grade 1: –40°C to +125°C

- Automotive Grade 2: –40°C to +105°C

- Automotive Grade 3: –40°C to +85°C

• High Supply Noise Rejection: –50 dBc

• Wide Freq. Range: 2.3 MHz to 170 MHz

• Small Industry Standard Footprints

- 2.5 mm x 2.0 mm

DSA1101 has a standby feature that allows it to

completely power-down when EN pin is pulled low. For

DSA1121, only the outputs are disabled when EN is

low. Both oscillators are available in industry standard

packages, including the small 2.5 mm x 2.0 mm, and

are “drop-in” replacements for standard 4-pin and 6-pin

CMOS quartz crystal oscillators.

- 3.2 mm x 2.5 mm

- 5.0 mm x 3.2 mm

• Excellent Shock and Vibration Immunity

- Qualified to MIL-STD-883

The DSA1105/25 is functionally equivalent to the

DSA1101/21, but it has lower drive strength for EMI

reduction.

• High Reliability

- 20x Better MTF than Quartz Oscillators

• Low Current Consumption

Functional Block Diagram

• Supply Range of 2.25 to 3.63V

• Standby and Output Enable Function

• Lead-Free and RoHS Compliant

Applications

• Automotive Infotainment

• Automotive ADAS

• Automotive Camera Module

• Automotive LIDAR and RADAR

Benefits

• Replace High Temperature Crystals and Quartz

Oscillators
