18QHTF21-104.000-PD

Overview

The 18QHTF21-104.000-PD is a crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 104 MHz and utilizes LVCMOS output logic. The device functions with a 1.8V supply voltage and includes a standby (power down) feature for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. This component is designed for applications requiring precise clock signals in space-constrained environments.

Feature Summary

• Supports LVCMOS output logic for standard digital interfacing
• Includes standby mode capability to reduce power consumption
• Utilizes a small form factor SMD package for surface mount assembly

Applications

• Portable electronic devices requiring low power operation
• Digital signal processing circuits
• Communication equipment clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a 104 MHz clock signal is required within a 2.0x1.6 mm footprint. Consider the 1.8V operating voltage and LVCMOS interface compatibility with your target logic family. Evaluate the need for standby functionality if power efficiency is critical for the application environment.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies and supply voltages. The 'PD' suffix indicates the inclusion of a power-down or standby control feature, distinguishing it from standard continuous-operation variants within the same physical package family.

Replacement Considerations

Direct substitutes include other 104 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical parameters such as phase noise and jitter before substitution. Cross-reference with manufacturer datasheets for equivalent performance metrics.
