Overview
The Silicon Labs 502AAA-ADAF is a CMEMS programmable oscillator with a 4-SMD, No Lead (DFN, LCC) package measuring 2.50mm x 2.00mm x 0.90mm. It operates on a supply voltage of 1.7V to 3.6V and supports frequencies from 32kHz to 100MHz. The device features LVCMOS output with tri-state control, ±20ppm frequency stability, and an operating temperature range of -20°C to 70°C. Maximum supply current is 6.5mA.
Feature Summary
- CMEMS technology for reliable clock generation
- LVCMOS output interface with tri-state enable/disable functionality
- Pre-programmed frequency customization via ordering notes
Applications
- Embedded systems requiring precise timing
- IoT devices needing low-power clock sources
- Microcontroller clock inputs
Procurement Notes
Verify the specific target frequency in Web Order Notes during procurement, as this model is programmed by Digi-Key. Confirm that the 4-SMD no-lead package dimensions and 1.7V-3.6V supply range match your design requirements. Ensure the -20°C to 70°C industrial temperature rating aligns with your operational environment constraints before finalizing orders.
Selection Notes
Select this component when a small footprint (2.5x2.0mm) and low voltage operation are required. It is suitable for applications needing ±20ppm stability without external tuning. Consider the 6.5mA max current draw for power budgeting. Verify compatibility with LVCMOS logic levels and tri-state control needs in the system architecture.
Part Context
This part belongs to the Si50x series of CMEMS programmable oscillators from Silicon Labs. It utilizes silicon MEMS technology to replace traditional quartz crystals, offering better shock resistance and smaller form factors. The series supports various output types and voltage ranges for diverse embedded applications.
Replacement Considerations
Consult official Silicon Labs documentation for direct cross-references within the Si50x family. Verify pinout compatibility and electrical specifications before substituting with other programmable oscillators.
