18QHTF21-20.83333-OE

Oscillators Overview

The 18QHTF21-20.83333-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 20.83333 MHz with an LVCMOS output type. The device supports a supply voltage of 1.8V and features enable/disable functionality. Frequency stability is specified at ±50ppm, and it functions within an operating temperature range of -40°C to 85°C. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• Supports enable/disable control for power management
• Compact 4-SMD no-lead surface mount package
• LVCMOS output signal compatibility

Oscillators Applications

• Embedded systems requiring precise clock signals
• Consumer electronics with low power constraints
• Industrial control modules operating in wide temperature ranges

Oscillators Procurement Notes

Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm the enable/disable feature and pinout configuration. Ensure the 1.8V supply requirement aligns with the target circuit design. Confirm that the 2.0x1.6mm footprint matches the PCB layout specifications before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a low-profile 2.0x1.6mm oscillator is required for space-constrained designs. The 1.8V supply voltage makes it suitable for modern low-voltage logic families. Consider the ±50ppm stability specification relative to system timing requirements and verify the LVCMOS interface compatibility with the receiving digital components.

Oscillators Part Context

This part belongs to the 18QHTF21 series of high-frequency oscillators from Mercury Electronics. The series offers various frequency options and package types. The 'OE' suffix typically denotes specific operational characteristics such as enable/disable functionality, distinguishing it from other variants in the same physical package family.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with identical 20.83333 MHz frequency and LVCMOS output. Verify that any replacement maintains the 1.8V supply voltage and 4-SMD no-lead package dimensions. Check if the substitute includes the enable/disable feature if power management is critical.
