Procurement Notes

Verify the specific suffix codes to confirm the exact frequency, package type, and temperature grade required for your design. Ensure compatibility with the I2C programming interface during integration. Check for moisture sensitivity levels and reflow soldering profile requirements to prevent damage during assembly. Confirm that the selected variant meets all regulatory compliance standards for your target market.

Selection Notes

Choose this component when LVDS outputs and 25 PPM stability are required within the specified voltage range. Consider the QFN-4 footprint constraints and thermal management needs for dense PCB layouts. Evaluate the need for programmability versus fixed-frequency alternatives based on production flexibility requirements. Ensure the operating temperature range aligns with the environmental conditions of the final application.

Part Context

The DSC8123CI2 belongs to the DSC8123 family of programmable MEMS oscillators. This series is known for its small form factor and ability to replace multiple crystal oscillator variants. It integrates the resonator and oscillator circuitry into a single chip, reducing board space and simplifying inventory management for manufacturers producing various timing solutions.

Replacement Considerations

Direct replacements may include other members of the DSC8123 family with different suffixes indicating varied frequencies or stability grades. Cross-referencing pinout and electrical specifications is essential when substituting with similar MEMS oscillators from other manufacturers. Verify that any alternative part supports the same LVDS output and I2C programming capabilities.
