Overview
The 18QHTF21-62.208-PD is a 62.208 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 device features a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. It includes a Standby (Power Down) function for energy management.
Feature Summary
- LVCMOS output interface
- Standby power down capability
- Compact 4-SMD no lead package
Applications
- Digital signal processing circuits
- Communication equipment clocking
- Embedded system timing references
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no lead footprint matches your PCB layout constraints to guarantee proper soldering and mechanical stability during assembly.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside a small form factor. The LVCMOS output is suitable for standard digital logic interfaces. Consider the standby feature if power efficiency during idle states is a priority. Verify that the 62.208 MHz frequency meets the specific timing needs of the target application without requiring external dividers.
Part Context
This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies while maintaining consistent electrical characteristics and package dimensions. The PD suffix indicates the inclusion of a power-down control pin, distinguishing it from standard continuous-operation variants within the same physical package family.
Replacement Considerations
Direct replacements must match the 62.208 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no lead package. Verify pinout compatibility and thermal performance. Cross-reference with other manufacturers offering similar low-profile oscillators with standby functionality.
