Overview
The 18QHTF21-82.000-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 82 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a power-down mode for standby functionality. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0x1.6 mm.
Feature Summary
- Supports LVCMOS output logic for digital interface compatibility
- Includes standby capability via power-down control
- Utilizes a surface-mount 4-SMD no-lead package
Applications
- General clock signal generation in electronic circuits
- Timing reference for digital systems requiring 82 MHz
- Embedded applications utilizing LVCMOS interfaces
Procurement Notes
Verify the specific operating temperature range and load capacitance requirements 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 design constraints to guarantee proper soldering and mechanical stability during assembly.
Selection Notes
Select this component when an 82 MHz timing source with LVCMOS outputs is required in a low-profile form factor. The 1.8V supply specification suits modern low-voltage digital designs. The integrated power-down feature offers energy efficiency benefits for battery-operated or power-sensitive applications compared to continuous-operation oscillators.
Part Context
This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products. The series includes various frequencies and packages, catering to diverse timing needs. Mercury Electronics has established itself as a supplier of crystals, oscillators, and filters since 1973, focusing on precision timing solutions.
Replacement Considerations
Compatible substitutes within the same series include models such as 18QHTF21-80.000-PD and 18QHTF21-51.200-PD, provided the frequency difference is acceptable for the application.
