• Integrated standby mode for power reduction
• Surface-mount 4-SMD no-lead package design

Oscillators Applications

• General purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application's specifications before procurement. Ensure the 1.8V supply voltage aligns with the system power rails. Confirm that the 4-SMD package dimensions fit within the designated PCB footprint constraints. Cross-reference the part number suffix to ensure the correct packaging and handling characteristics are obtained from authorized distributors.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS compatibility. The integrated power-down feature makes it suitable for battery-operated devices where standby current consumption is critical. Consider the 4-SMD form factor for space-constrained designs. Evaluate if the standard XO stability meets the system's jitter and phase noise requirements compared to TCXO alternatives.

Oscillators Part Context

This model belongs to the 18QHTF32 series of quartz crystal oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized small outline package. Mercury Electronics specializes in frequency control components, leveraging decades of experience in quartz crystal manufacturing to provide reliable timing solutions for electronic systems.

Oscillators Replacement Considerations

Direct substitutes must match the 14.753 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Check equivalent parts from other manufacturers ensuring identical pinout and electrical characteristics. Verify that any replacement maintains the same standby functionality and operating temperature range.
