Overview
The 18QHTF21-13.52915-OE is a 13.52915 MHz crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a supply voltage of 1.8V and utilizes LVCMOS output logic. The component features an Enable/Disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This surface-mount device is designed for precision timing applications requiring low profile and stable frequency generation.
Feature Summary
- Integrated enable/disable functionality for dynamic power control
- Compact 4-SMD no-lead package design suitable for space-constrained layouts
- LVCMOS output logic compatible with standard digital interfaces
Applications
- Portable electronic devices requiring low power consumption
- Communication equipment needing precise clock signals
- Consumer electronics with limited board space
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the LVCMOS output levels are compatible with the receiving logic inputs to guarantee signal integrity and proper operation within the specified temperature range.
Selection Notes
Select this component when a small form factor and low operating voltage are critical. The 1.8V supply makes it suitable for battery-powered or low-voltage digital systems. Consider the enable pin feature if power efficiency during idle states is a priority. Ensure the 13.52915 MHz frequency matches the exact requirement of the target application without need for external dividers.
Part Context
This part belongs to the QHTF series from Mercury Electronic, which offers various hermetic ceramic leadless SMD packages. The series supports frequencies from 1.0 MHz to 200 MHz across different supply voltages. Mercury Electronic is a Taiwan-based manufacturer specializing in quartz crystals and oscillators, established as a pioneer in the local industry since 1973.
Replacement Considerations
Direct substitutes include other variants within the same QHTF series such as 18QHTF21-15.300-OE or 18QHTF21-33.200-OE, provided the frequency difference is acceptable for the application. Cross-reference with other manufacturers offering similar 2.0x1.6mm LVCMOS oscillators if Mercury parts are unavailable.
