18QHTF21-32.250-PD

Oscillators Overview

The 18QHTF21-32.250-PD is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 32.25 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby (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

• Integrates LVCMOS output logic for standard digital interface compatibility
• Features a standby mode to reduce power consumption during inactive periods
• Utilizes a leadless SMD package for surface-mount assembly efficiency

Oscillators Applications

• General clock signal generation in electronic circuits
• Timing reference for low-voltage digital systems
• Embedded devices requiring compact oscillator solutions

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD no-lead footprint matches the PCB layout design rules to guarantee proper soldering and mechanical stability.

Oscillators Selection Notes

Select this component when a small form factor is required alongside standard LVCMOS signaling. The integrated standby feature makes it suitable for battery-powered or power-sensitive applications. Verify that the operating temperature range meets the environmental conditions of the intended deployment scenario.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard XO oscillators from Mercury Electronics. The series offers various frequencies within a consistent 2.0x1.6 mm package. The 'PD' suffix indicates the inclusion of a power-down control capability, distinguishing it from continuous-output variants.

Oscillators Replacement Considerations

Direct substitutes must match the 32.25 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering identical footprint and electrical specifications.
