Overview
The 18QHTF21-60.800-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 60.8 MHz and utilizes LVCMOS output logic levels. The device requires a 1.8V supply voltage and features a standby mode for power down functionality. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount assembly on printed circuit boards.
Feature Summary
- Supports low-voltage operation with 1.8V supply requirement
- Includes standby function for power management
- Utilizes LVCMOS output interface
Applications
- Battery-powered portable devices
- General digital system clocking
- Embedded electronics applications
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply rail is stable and within the operational limits defined in the official datasheet. Ensure the PCB footprint matches the 4-SMD No Lead package dimensions to guarantee proper soldering and electrical connection during assembly.
Selection Notes
Select this component when a precise 60.8 MHz clock signal is required for LVCMOS-compatible circuits. Consider the 1.8V operating voltage and standby capability for power-sensitive designs. Evaluate the thermal performance and size constraints of the 4-SMD package relative to the available board space and environmental conditions of the target application.
Part Context
This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies while maintaining consistent package and electrical characteristics. The 'PD' suffix typically indicates the inclusion of a power-down or standby feature, distinguishing it from standard continuous-operation variants within the same product family.
Replacement Considerations
Direct substitutes include other 60.8 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation, such as the 18QHTF21-60.800 from compatible manufacturers. Verify pinout compatibility and electrical parameters before substitution.
