Overview
The 18QHTF21-94.697-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 94.697 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a Standby function for power down control. It is housed in a compact 4-SMD, No Lead package suitable for surface-mount applications.
Feature Summary
- Supports low-voltage operation with 1.8V supply requirement
- Integrates standby capability for power management
- Provides LVCMOS digital output signals
Applications
- Digital signal processing systems
- Communication equipment clocking
- Embedded system timing references
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Ensure the 1.8V supply rail stability matches the component specifications. Confirm the 4-SMD no-lead footprint dimensions align with the target PCB layout to guarantee proper soldering and mechanical retention during assembly processes.
Selection Notes
Select this model when a precise 94.697 MHz reference is required in space-constrained designs. The LVCMOS interface ensures compatibility with standard digital logic families. The integrated standby feature allows for energy optimization in battery-operated or power-sensitive portable devices requiring reliable high-frequency timing sources.
Part Context
This component belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequency options within a standardized small outline package. The PD suffix typically indicates a specific tape-and-reel packaging configuration for automated manufacturing integration.
Replacement Considerations
Direct substitutes include other 18QHTF21 variants with identical pinouts but different frequencies, such as 18QHTF21-96.768-PD or 18QHTF21-50.000-PD, provided the circuit design accommodates the frequency change. Verify electrical parameters match the application needs.
