Overview
The 18QHTF21-93.333-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 93.333 MHz with an LVCMOS output logic level. The device requires a 1.8V supply voltage and includes a power-down (standby) function for energy management. It is housed in a compact 4-SMD, no-lead package measuring 2.0mm x 1.6mm.
Feature Summary
- LVCMOS output interface
- Integrated power-down capability
- Compact surface-mount form factor
Applications
- Digital signal processing systems
- Communication equipment timing
- Embedded control circuits
Procurement Notes
Verify the specific frequency suffix matches the required 93.333 MHz specification, as the series supports various frequencies. Confirm the 1.8V operating voltage aligns with system power rails. Ensure the 4-SMD no-lead package type is compatible with the PCB footprint design. Check RoHS compliance status if environmental regulations apply to the final assembly.
Selection Notes
Select this component when a precise 93.333 MHz clock source is needed for low-voltage digital circuits. The LVCMOS output ensures compatibility with standard logic families. The power-down feature allows for battery conservation in portable devices. The small 2.0x1.6mm package is suitable for space-constrained designs requiring high-frequency stability.
Part Context
This part belongs to the 18QHTF21 series of standard XO oscillators from Mercury Electronics. The series offers various frequencies with consistent 1.8V operation and LVCMOS outputs. The 'PD' suffix indicates the inclusion of a power-down pin or function, distinguishing it from basic models without standby capabilities within the same physical package family.
Replacement Considerations
Direct substitutes include other 18QHTF21 series variants with identical 93.333 MHz frequency, 1.8V supply, and LVCMOS output. Verify that any replacement maintains the 4-SMD no-lead package dimensions and power-down functionality to ensure mechanical and electrical compatibility.
