Overview
The 18QHTF21-9.4935-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 9.4935 MHz and utilizes LVCMOS output logic levels. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature for power management. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0x1.6 mm, designed for surface-mount applications requiring precise timing signals.
Feature Summary
- Integrates enable/disable functionality for efficient power control
- Delivers stable LVCMOS signal outputs for digital interfacing
- Utilizes a miniature 4-SMD no-lead footprint for space-constrained designs
Applications
- Consumer electronics timing circuits
- Industrial control system clocks
- Embedded data communication interfaces
Procurement Notes
Verify the specific ordering suffix against official Mercury Electronics documentation to confirm exact electrical tolerances and temperature ranges. Ensure the component matches the required 1.8V supply specification and LVCMOS interface requirements for your target application before finalizing procurement orders.
Selection Notes
Select this oscillator when a low-voltage 1.8V operation is required alongside precise frequency stability. The integrated enable pin allows for dynamic power management in battery-operated devices. Consider the small 2.0x1.6 mm package size if board real estate is limited compared to larger standard packages.
Part Context
This component belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequency options within a standardized 4-SMD package form factor. These oscillators are designed to provide reliable clock signals for modern electronic systems requiring compact timing solutions.
Replacement Considerations
Direct substitutes include other 18QHTF21 series variants with identical package and voltage specifications but different frequencies, such as 18QHTF21-8.640-OE or 18QHTF21-21.200-OE, provided the frequency difference is acceptable for the circuit design.
