Overview
The 18QHTF21-93.330-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 93.330 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function 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
- Integrates LVCMOS output logic for digital interface compatibility
- Supports standby mode to reduce power consumption during idle periods
- Utilizes a lead-free surface-mount package for automated assembly
Applications
- Digital signal processing systems requiring precise timing references
- Communication equipment utilizing standard clock frequencies
- Embedded systems with low-voltage power constraints
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against the system design specifications before procurement. Confirm that the 1.8V supply voltage aligns with the target circuit's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout guidelines provided in the official datasheet to prevent soldering defects.
Selection Notes
Select this component when a fixed 93.330 MHz frequency is required for synchronous data transmission or processing. The choice is driven by the need for a low-profile surface-mount solution compatible with 1.8V logic levels. Consider the standby feature if power efficiency is a critical design parameter for the application environment.
Part Context
This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronic Ind. Co., Ltd. The series offers various frequency options within a consistent 2.0x1.6mm form factor. The PD suffix indicates the inclusion of a power-down control pin, distinguishing it from continuous-operation variants within the same physical package family.
Replacement Considerations
Direct substitutes include other 93.330 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical parameters such as phase noise and jitter before swapping manufacturers.
