DSA1103/23

Low-Jitter Precision LVDS Oscillator for Automotive

Features

General Description

• Automotive AEC-Q100 Qualified

The DSA1103 and DSA1123 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

automotive applications like in-vehicle networking and

autonomous driving.

• Wide Frequency Range: 2.3 MHz to 460 MHz

(LVDS)

• Low RMS Phase Jitter: <1 ps (typ.)

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

• Wide Temperature Range:

- 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

• Small Industry Standard Footprints

- 2.5 mm x 2.0 mm (VDFN)

DSA1103 has a standby feature that allows it to

completely power-down when pin 1 is pulled low. For

DSA1123, only the outputs are disabled when pin 1 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 6-pin LVDS

crystal oscillators.

- 3.2 mm x 2.5 mm (VDFN & Wettable Flank)

- 5.0 mm x 3.2 mm (CDFN)

• Excellent Shock and Vibration Immunity

- Qualified to MIL-STD-883

• High Reliability

- 20x Better MTBF than Quartz Oscillators

• Low Current Consumption
