DSC2311KI2-R0059
Crystal-less™ Configurable Clock Generator
General Description
DSC2311KI2-R0059 is a crystal-less clock generator
that is factory configurable to simultaneously output
two separate frequencies from 2.3 to 170MHz. 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
enhance reliability
and accelerate product
development, while meeting stringent clock
performance criteria for a variety of consumer
electronics, communications, and storage applications.
DSC2311KI2-R0059 has an 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. This requires a PCB
footprint equivalent to that of a 1.0mm x 1.0mm
crystal-based clock generator.
Features
• Two simultaneous LVCMOS outputs:
- 25MHz
- 12MHz
• Low RMS phase jitter: <1ps (typical)
• ±25ppm frequency stability
• -40°C to +85°C industrial 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
• Programmable output strength for EMI reduction
and signal integrity optimization
• Supply range of 2.25 to 3.6V
• AEC-Q100 automotive qualified
• 6-pin 2.5mm x 2.0mm TDFN package
Applications
• Consumer Electronics
• Camera and Imaging Modules
• Home Automation
• Industrial and Power Conversion
• Mobile Communications, Internet, and Sensor Devices
• Solid State, Hard Drive, and Flash Drive Storage
• Automotive
