Overview
The DSC8123BI2T is an unprogrammed MEMS oscillator manufactured by Microchip Technology. It operates within a frequency range of 10 MHz to 460 MHz and provides a frequency stability of 10 ppm. The device supports LVDS output format and functions with a supply voltage between 2.25 V and 3.6 V. It is housed in a QFN-4 package measuring 2.5 mm by 2 mm, suitable for surface mount installation. The component is rated for operation from -40°C to +85°C.
Feature Summary
- Utilizes silicon MEMS technology for high reliability and shock immunity
- Offers programmable frequency generation capabilities
- Supports LVDS output interface for high-speed signaling
Applications
- General clocking for digital systems
- Data communication interfaces
- Consumer electronics requiring stable timing sources
Procurement Notes
Verify the specific suffix 'I2T' against official Microchip documentation to confirm package type and tape/reel specifications. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles defined in the datasheet. Confirm that the unprogrammed status aligns with system design requirements for post-manufacturing configuration.
Selection Notes
Select this component when a small footprint QFN-4 package is required alongside LVDS outputs. Consider the 10 ppm stability requirement and the 2.25 V to 3.6 V operating range. Evaluate thermal performance within the -40°C to +85°C industrial temperature range for the target application environment.
Part Context
This part belongs to the DSC8123 family of unprogrammed MEMS oscillators. These devices are designed as drop-in replacements for traditional quartz crystals and resonators, offering superior performance characteristics including lower phase jitter and higher vibration resistance while maintaining a compact form factor.
Replacement Considerations
Direct substitutes include other DSC8123 variants with compatible pinouts and electrical parameters. Verify package dimensions and output format compatibility before substitution.
