Overview
The 18QHTF21-107.500-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 107.5 MHz and utilizes LVCMOS output logic levels. The device is designed for a supply voltage of 1.8V and includes a standby or power-down function to manage energy consumption during inactive periods. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm, suitable for surface-mount assembly.
Feature Summary
- Supports low-voltage operation at 1.8V
- Includes standby and power-down functionality
- Features LVCMOS output interface
Applications
- Digital signal processing systems
- Communication equipment clocking
- Embedded control circuits
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure that the PCB footprint matches the 2.0x1.6mm SMD package dimensions. Confirm that the 1.8V supply rail is stable and within the operational limits specified in the official datasheet to maintain signal integrity.
Selection Notes
Select this component when a precise 107.5 MHz reference is required for LVCMOS-compatible digital interfaces. Consider the 1.8V operating voltage and the availability of power-down modes for applications requiring reduced standby current. Evaluate the small form factor against available board space constraints.
Part Context
This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized 2.0x1.6mm package. The 'PD' suffix indicates the inclusion of power-down capabilities, distinguishing it from continuous-operation variants.
Replacement Considerations
Direct replacements must match the 107.5 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar low-profile oscillators if Mercury Electronics stock is unavailable.
