Overview
The 18QHTF21-75.350-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 75.35 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a Standby (Power Down) function for power management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.
Feature Summary
- Supports LVCMOS output logic for digital interface compatibility
- Includes Standby (Power Down) functionality to reduce power consumption
- Designed for low-profile surface-mount integration
Applications
- General-purpose digital timing circuits
- Embedded systems requiring precise clock references
- Consumer electronics with space constraints
Procurement Notes
Verify the specific suffix 'PD' confirms the Standby (Power Down) feature rather than Enable/Disable control. Ensure the 1.8V supply voltage aligns with target system rails. Confirm the 4-SMD No Lead package dimensions match PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when a 75.35 MHz clock signal is required with low-power standby capabilities. Compare against other variants in the 18QHTF21 series to ensure the correct output logic and voltage levels meet design specifications. Validate thermal performance within the specified operating temperature range.
Part Context
This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount crystal oscillators. The series offers various frequencies and voltage options. Mercury Electronics is a established manufacturer of frequency control products, providing quartz-based timing solutions for industrial and commercial applications.
Replacement Considerations
Direct substitutes include the 18QHTF21-75.350-OE, which shares the same frequency and package but may differ in control logic (Enable/Disable vs. Standby). Verify functional equivalence regarding power management modes before substitution.
