DSA2311KI1-R0016VAO

Crystal-less™ Configurable Clock Generator

for Automotive

General Description

Features

DSA2311KI1-R0016VAO is a crystal-less clock

generator that is factory configurable to

simultaneously output two separate frequencies

from 2.3 to 170MHz.

• AEC-Q100 automotive qualified

• Two simultaneous LVCMOS outputs:

- 24MHz

- 50MHz

The clock generator uses proven silicon MEMS

technology to provide low jitter and high frequency

stability across a wide range of supply voltages and

temperatures. By eliminating the external quartz

crystal, crystal-less clock generators significantly

• Low RMS phase jitter: <1ps (typical)

• ±50ppm frequency stability

• -40°C to +85°C (Grade 3) temperature range

• High supply noise rejection: -50dBc

• High shock & vibration immunity

- Qualified to MIL-STD-883

• High reliability

- 20x higher MTBF than crystal-based clock

generator designs

• Supply range of 2.25 to 3.6V

• 6-pin 2.5mm x 2.0mm TDFN package

enhance reliability

and

accelerate

product

development, while meeting stringent clock

performance criteria for a variety of consumer

electronics, communications, and storage applications.

DSA2311KI1-R0016VAO has

output

enable/disable feature allowing it to disable the

outputs when OE is low. The device is available in a

space-saving 6-pin 2.5mm x 2.0mm TDFN package

that needs only a single external bypass capacitor.

Applications

• Automotive Infotainment

• Automotive ADAS

• Automotive Camera Module

• Automotive LIDAR and RADAR
