Overview
The 18QHTF21-13.528-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 13.528 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and 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 component is part of the QuikXO series, designed for fast delivery and reliable timing applications.
Feature Summary
- LVCMOS output logic for digital interface compatibility
- Integrated Enable/Disable pin for power control
- Compact 4-SMD no-lead surface mount package
Applications
- General purpose clock signal generation
- Embedded system timing references
- Consumer electronics circuit boards
Procurement Notes
Verify the specific frequency tolerance and operating temperature range against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD footprint matches the PCB layout design. Check for RoHS compliance status if required by project specifications.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside a precise 13.528 MHz reference. The LVCMOS output is suitable for direct connection to standard digital logic inputs. Consider the small 2.0x1.6mm package size for space-constrained designs requiring surface-mount assembly.
Part Context
This oscillator belongs to Mercury's QuikXO series, which focuses on CMOS output clock oscillators with rapid availability. The brand specializes in frequency-control products including quartz crystals and filters. The model number indicates a specific frequency variant within their standard XO lineup.
Replacement Considerations
Direct substitutes must match the 13.528 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify equivalent electrical characteristics such as phase noise and stability before cross-referencing other manufacturers' components.
