AMJDEFJ-A11

Overview

The Abracon AMJDEFJ-A11 is a MEMS-based standard clock oscillator from the AMJD series, housed in a compact 4-VDFN package measuring 3.20mm x 2.50mm with a height of 0.90mm. It operates on a supply voltage range of 1.71V to 3.63V and draws a typical current of 1.3mA. The device provides a single CMOS output at either 50MHz or 100MHz, selected via pin configuration. It maintains a frequency stability of ±25ppm across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Pin-configurable selection between two distinct output frequencies
• MEMS technology for enhanced reliability and shock resistance
• Low power consumption optimized for portable applications
• CMOS output compatible with standard digital logic

Applications

• Portable consumer electronics requiring low power clocks
• Industrial control systems needing stable timing references
• Communication modules utilizing configurable frequency inputs
• Embedded computing platforms with space constraints

Procurement Notes

Verify the specific suffix and packaging variant when ordering, as availability may vary by reel or bulk quantity. Confirm that the pin configuration matches the required frequency selection for your design. Ensure compliance with RoHS3 standards and check moisture sensitivity levels for proper handling during assembly processes.

Selection Notes

Choose this component when a small footprint and dual-frequency capability are required without software reprogramming. It serves as a direct replacement for fixed-frequency oscillators where system flexibility is needed. Consider the 1.3mA typical current draw for battery life calculations and ensure the 3.2x2.5mm package fits the PCB layout constraints.

Part Context

This part belongs to the Abracon AMJD series, which focuses on power-optimized MEMS oscillators. The series offers various package sizes and frequency options, allowing designers to select components based on size and performance needs. The AMJDEFJ-A11 specifically targets applications requiring a balance between miniaturization and functional configurability.

Replacement Considerations

Direct substitutes within the same family include AMJDEFH-A11T (same specs, different package) and AMJDGFJ-A11T (different package). Verify pinout compatibility before swapping packages. No other manufacturers offer identical pin-configurable MEMS oscillators in this exact form factor.
