Overview
The 18QHTF21-92.900-PD is a crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 92.9 MHz and utilizes LVCMOS output logic levels. The device functions with a supply voltage of 1.8V and incorporates power-down (PD) capability to manage energy consumption. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.
Feature Summary
- Integrates power-down functionality for reduced standby current
- Provides standard LVCMOS signal output compatibility
- Designed for low-voltage operation at 1.8V
Applications
- Battery-powered portable electronic devices
- Systems requiring strict power management protocols
- Compact consumer electronics with limited board space
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply rail stability meets the oscillator's operational specifications. Ensure the PCB footprint matches the 2.0x1.6 mm SMD no-lead package dimensions to prevent assembly errors during manufacturing.
Selection Notes
Select this component when a small form factor and low voltage operation are primary constraints. The integrated power-down feature makes it suitable for applications where standby power consumption must be minimized. Ensure the host system supports LVCMOS signaling standards to guarantee proper interface compatibility without additional level shifting.
Part Context
This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz timing solutions. The manufacturer has produced frequency control products since 1973, establishing expertise in crystal oscillators and filters. This specific model represents a standard XO variant optimized for modern low-power digital applications.
Replacement Considerations
Direct substitutes include other 18QHTF21 variants with different frequencies such as 18QHTF21-51.200-PD or 18QHTF21-96.768-PD, provided the frequency difference is acceptable for the application.
