18QHTF21-30.210-PD

Oscillators Overview

The 18QHTF21-30.210-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 30.21 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Integrates standby and power-down functionality
• Provides LVCMOS output signal compatibility

Oscillators Applications

• General clock generation in embedded systems
• Timing reference for digital logic circuits
• Portable electronic devices requiring low power consumption

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 30.21 MHz specification, as the 18QHTF21 series offers multiple frequency options. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD no-lead package footprint fits the PCB layout constraints. Check for RoHS compliance if required by project standards.

Oscillators Selection Notes

Select this component when a precise 30.21 MHz timing source is needed with minimal power usage. The LVCMOS interface ensures direct compatibility with standard digital inputs. The small 2.0x1.6mm form factor is suitable for space-constrained designs. Consider the power-down feature if battery life optimization is a priority.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically features various frequencies and supply voltages. The 'PD' suffix indicates the inclusion of a power-down control pin, distinguishing it from always-on variants within the same package family.

Oscillators Replacement Considerations

Direct substitutes must match the 30.21 MHz frequency, 1.8V voltage, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility, particularly for the enable/power-down pin. Cross-reference with other manufacturers offering similar ultra-small XO packages.
