DSC1121AE1-008.0000T

Oscillators Overview

The DSC1121AE1-008.0000T is a MEMS oscillator from the DSC1121 series, manufactured by Microchip Technology. It operates at a frequency of 8 MHz with a stability of ±50 ppm over an industrial temperature range of -20°C to +70°C. The device utilizes a CMOS output format and functions within a supply voltage range of 2.25 V to 3.6 V. It is housed in a compact 6-VDFN package measuring 5.0 mm x 7.0 mm with a maximum height of 0.85 mm. The typical current consumption is 31 mA.

Oscillators Feature Summary

• MEMS-based technology for enhanced reliability and shock resistance compared to traditional quartz crystals.
• Integrated Enable/Disable function allows for power management control during inactive periods.
• CMOS output format provides direct compatibility with digital logic interfaces.

Oscillators Applications

• Industrial control systems requiring stable timing references.
• Consumer electronics utilizing low-power microcontrollers.
• Communication equipment needing precise clock synchronization.

Oscillators Procurement Notes

Verify the specific suffix 'AE1' confirms the -20°C to +70°C temperature grade and ±50 ppm stability. Ensure the 6-VDFN package dimensions align with PCB footprint requirements. Confirm the CMOS output type matches the target circuit's input logic levels. Cross-reference the manufacturer part number against official Microchip databases to avoid counterfeit components.

Oscillators Selection Notes

Select this component when a balance between performance and cost is required for general-purpose timing applications. The ±50 ppm stability is suitable for standard UART, SPI, or I2C interfaces where tight jitter specifications are not critical. Consider the 31 mA current draw for battery-operated designs, as lower power alternatives may exist in other series.

Oscillators Part Context

This part belongs to the DSC1121 family of high-performance MEMS oscillators. The family offers various frequencies, packages, and stability grades. The 'AE1' designation specifically indicates the automotive-grade temperature range (extended commercial) and standard stability option within the 6-VDFN form factor.

Oscillators Replacement Considerations

Direct parameter-equivalent substitutes include other DSC1121 variants with matching 8 MHz frequency, CMOS output, and 6-VDFN packaging. Verify that any replacement maintains the same ±50 ppm stability and -20°C to +70°C operating range to ensure system compatibility.
