Overview
The 18QHTF21-102.425-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 102.425 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, suitable for surface-mount assembly.
Feature Summary
- LVCMOS output logic interface
- Standby (Power Down) capability
- Compact 4-SMD, No Lead package
Applications
- Low-power electronic systems requiring precise timing
- Digital signal processing circuits
- Communication equipment clock sources
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD No Lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.
Selection Notes
Select this component when a 102.425 MHz clock signal is required with low power consumption constraints. The 1.8V operating voltage makes it suitable for modern low-voltage digital logic families. Consider the standby feature if power management during idle states is a critical design requirement for the application.
Part Context
This part belongs to the QHTF series of crystal oscillators from Mercury Electronics. The series typically offers standard frequencies with LVCMOS outputs. The '18' prefix indicates the 1.8V supply voltage variant, while 'PD' denotes the inclusion of a power-down pin or function for enhanced power efficiency in portable or battery-operated devices.
Replacement Considerations
Direct substitutes within the same series include other frequency variants such as 18QHTF21-100.000-PD or 18QHTF21-102.000-PD, provided the frequency difference is acceptable. Cross-referencing with similar 1.8V LVCMOS oscillators from other manufacturers requires matching package dimensions and electrical characteristics.
