Key Features
- Crystal-less MEMS clock generation eliminates external quartz crystal, reducing BOM and board area
- Two independently configurable output clocks with maximum frequency of 170 MHz
- Wide supply voltage range of 2.25 V to 3.6 V for compatibility with 2.5 V and 3.3 V digital systems
- Small 6-pin SOIC package (R-PDSO-N6) for space-constrained timing distribution designs
- MEMS oscillator technology providing improved vibration and shock resistance versus crystal resonators
Applications
DSC2311KE2-R0001T is used in networking equipment, FPGAs, and industrial control systems that require clean reference clocks up to 170 MHz without the fragility and supply-chain variability of quartz crystals. The dual-output configuration enables simultaneous distribution of different clock frequencies to multiple subsystems such as a processor core and a communication interface from a single 3.3 V clock source. It also suits portable instruments and wearable devices where vibration immunity and compact form factor are priorities over traditional crystal oscillator solutions.

Frequently Asked Questions
How does DSC2311KE2-R0001T eliminate the external quartz crystal, and what reliability advantage does this provide?
DSC2311KE2-R0001T uses MEMS resonator technology internally, removing the need for an external quartz crystal. MEMS elements are inherently more resistant to mechanical shock and vibration than quartz, and the integrated design eliminates a separate crystal component with its own lead time, handling sensitivity, and frequency tolerance variations.
Can DSC2311KE2-R0001T provide two different output frequencies simultaneously for a dual-bus FPGA design?
Yes. DSC2311KE2-R0001T has two independently configurable clock outputs, each programmable up to 170 MHz, allowing an FPGA design to simultaneously receive different clock frequencies on its core fabric and its high-speed I/O interfaces from a single device operating from a 3.3 V rail.
What supply voltage range is compatible with DSC2311KE2-R0001T, and does it work in a 2.5 V digital system?
DSC2311KE2-R0001T operates from 2.25 V to 3.6 V supply voltage, which encompasses both 2.5 V and 3.3 V digital system power rails, giving designers flexibility to use the same clock generator part across different board power domains without circuit modifications.
For high-volume production, how does using DSC2311KE2-R0001T affect BOM management compared to stocking a discrete crystal and oscillator circuit?
Replacing a discrete crystal plus oscillator circuit with DSC2311KE2-R0001T reduces the clock timing BOM to a single 6-pin component, simplifying procurement, reducing assembly steps, and eliminating crystal-specific PCB layout rules such as guard rings and keep-out areas that are mandatory on quartz resonator designs.
