Overview
The 18QHTF21-100.003-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a nominal frequency of 100.003 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a standby or power-down feature for energy management. 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
- Integrates standby mode for power reduction
- Provides LVCMOS signal output compatibility
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 procurement. Confirm that the 1.8V supply rail is stable within the operational limits defined in the official datasheet. Ensure the PCB footprint matches the 4-SMD no-lead package specifications to guarantee proper soldering and electrical connection.
Selection Notes
Select this component when a precise 100.003 MHz reference is required in space-constrained designs. The 1.8V operating voltage makes it suitable for modern low-power digital systems. Consider the LVCMOS interface for direct compatibility with standard logic families without additional level shifting components.
Part Context
This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequency options within a standardized 2.0x1.6 mm package. The 'PD' suffix indicates the inclusion of a power-down control function, distinguishing it from continuous-operation variants in the same family.
Replacement Considerations
Direct substitutes include other 18QHTF21 series parts with identical pinout and voltage but different frequencies, such as 18QHTF21-51.200-PD. Cross-referencing with generic 2.0x1.6mm LVCMOS oscillators requires verification of electrical parameters and mechanical tolerances.
