Overview
The 18QHTF21-10.727-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 10.727 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a standby power-down mode for energy efficiency. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0 x 1.6 mm.
Feature Summary
- Supports low-voltage operation at 1.8V
- Includes standby power-down functionality
- Utilizes LVCMOS output interface
Applications
- General clock signal generation
- Embedded system timing references
- Portable electronic devices requiring low power consumption
Procurement Notes
Verify the exact frequency tolerance and load capacitance requirements against your circuit design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints to guarantee proper soldering and mechanical stability during assembly.
Selection Notes
Select this component when a precise 10.727 MHz reference is required in space-constrained applications. The 1.8V operating voltage makes it suitable for modern low-power digital circuits. Consider the LVCMOS output compatibility with your receiving logic gates. The small 2.0x1.6mm package allows for high-density board layouts compared to larger oscillator packages.
Part Context
This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in frequency control products. The series offers various frequencies within a standardized 4-SMD no-lead form factor. Mercury Electronics has been a pioneer in the crystal industry since 1973, providing reliable oscillators for diverse electronic applications.
Replacement Considerations
Direct substitutes must match the 10.727 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package dimensions. Verify pinout compatibility and electrical characteristics such as phase noise and jitter if available in official datasheets.
