Overview
The 18QHTF21-75.9255-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 75.9255 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features a Standby (Power Down) control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.
Feature Summary
- LVCMOS output logic for digital interface compatibility
- Standby (Power Down) control capability
- Compact 4-SMD No Lead surface mount package
Applications
- Battery-powered portable devices
- General purpose clock signal generation
- Digital circuit timing references
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against the target system design before procurement. Confirm that the 1.8V supply voltage aligns with the host controller's I/O levels. Ensure the 4-SMD No Lead footprint matches the PCB layout silkscreen and solder mask definitions to prevent assembly defects during manufacturing.
Selection Notes
Select this component when a precise 75.9255 MHz clock source is required with low power consumption capabilities. The 1.8V operating voltage makes it suitable for modern low-voltage digital systems. The integrated standby feature allows for dynamic power management in battery-operated applications where energy efficiency is critical.
Part Context
This part belongs to the QHTF series of surface-mount crystal oscillators from Mercury Electronics. The '18' prefix indicates the 1.8V supply voltage requirement, while 'PD' denotes the Standby (Power Down) control option. This series is designed for applications requiring small form factors and reliable frequency stability in consumer electronics.
Replacement Considerations
Direct substitutes include other 75.9255 MHz LVCMOS oscillators with identical 1.8V supply and 4-SMD No Lead packaging. Verify pinout compatibility and electrical specifications such as current consumption and startup time before substitution.
