DSC8123CI2T

Overview

The DSC8123CI2T is an unprogrammed MEMS oscillator from Microchip Technology, housed in a 6-SMD, No Lead package. It operates within a supply voltage range of 2.25 V to 3.6 V and supports frequencies from 2.3 MHz to 460 MHz. The device features LVDS output format with ±25 ppm frequency stability and low RMS phase jitter under 1 ps. It functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Utilizes silicon MEMS technology for high reliability and shock immunity
• Provides low RMS phase jitter performance typical of less than 1 ps
• Offers wide supply noise rejection capability of -50 dBc
• Includes standby and output enable functions for power management

Applications

• High-performance standard clock generation
• Data communication systems requiring precise timing
• Industrial equipment operating in extreme temperatures
• Portable devices needing low current consumption

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when sourcing. Confirm the factory pack quantity matches your production line requirements. Ensure the component meets RoHS compliance standards for your region. Check for any export control data classifications relevant to your location before finalizing orders.

Selection Notes

Select this part for applications requiring high stability and low jitter without programming complexity. Compare against quartz oscillators for superior vibration immunity. Consider the 6-SMD footprint for compact board designs. Verify that the LVDS output interface aligns with your target load requirements.

Part Context

This component belongs to the DSC8123 family of programmable low-jitter precision oscillators. It shares core MEMS architecture with other variants like the DSC8123BI5 but differs in package and stability specifications. The CI2 designation typically denotes industrial temperature range and specific stability ratings within the product line.

Replacement Considerations

Direct substitutes include other DSC8123 series members such as DSC8123CI2 or DSC8123AI2 if package compatibility allows. Cross-reference pinouts and electrical parameters carefully. Ensure replacement parts maintain the required LVDS output format and supply voltage range.
