18QHTF21-30.700-PD

Oscillators Overview

The 18QHTF21-30.700-PD is a 30.7 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It utilizes LVCMOS output logic and operates on a 1.8V supply voltage. The device features 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 LVCMOS output signaling
• Includes standby and power-down functionality
• Utilizes quartz-based frequency control technology

Oscillators Applications

• General electronic circuit timing
• Low-power embedded systems
• Digital signal processing interfaces

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target system design before procurement. Confirm that the 1.8V operating voltage aligns with the host controller's I/O levels. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a precise 30.7 MHz reference clock is required for LVCMOS-compatible digital circuits. The choice is driven by the need for a small 2.0x1.6mm form factor and integrated power management capabilities. Consider the 1.8V supply constraint and ensure the application benefits from the standby mode to reduce overall system power consumption during idle periods.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount oscillators. The series offers various standard frequencies within a consistent 4-SMD package. The 'PD' suffix indicates the inclusion of power-down control, distinguishing it from continuous-operation variants. This family targets applications requiring reliable quartz stability in space-constrained designs.

Oscillators Replacement Considerations

Direct substitutes must match the 30.7 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pin compatibility and thermal characteristics. Cross-reference with other Mercury 18QHTF21 variants or equivalent industry-standard oscillators ensuring identical electrical parameters and physical dimensions.
