18QHTF32-15.624-PD

Oscillators Overview

The 18QHTF32-15.624-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 15.624 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and features a Standby (Power Down) control function for power management. It is housed in a compact 4-SMD, No Lead surface-mount package suitable for automated assembly processes.

Oscillators Feature Summary

• LVCMOS output interface for digital logic compatibility
• Integrated standby mode for power reduction
• Surface-mount construction for PCB integration

Oscillators Applications

• Precision frequency generation in digital circuits
• Clock source for microprocessors and FPGAs
• Embedded systems requiring low-power operation

Oscillators Procurement Notes

Verify the specific suffix 'PD' indicates the Standby (Power Down) functionality as documented in official Mercury Electronics datasheets. Confirm that the 1.8V supply requirement aligns with the target system's voltage rails. Ensure the 4-SMD No Lead package dimensions match the design footprint constraints before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a 15.624 MHz clock signal is required with low-voltage 1.8V operation. The choice is appropriate for designs prioritizing power efficiency through the standby feature. Consider the surface-mount form factor for space-constrained layouts. Verify that LVCMOS output swing meets the input requirements of the downstream logic components.

Oscillators Part Context

This part belongs to the 18QHTF32 series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies and supply voltages. The '-PD' suffix specifically denotes the inclusion of a power-down control pin, distinguishing it from standard continuous-operation variants within the same package family.

Oscillators Replacement Considerations

Direct substitutes must match the 15.624 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify that any alternative also includes the standby control feature if power management is critical. Cross-reference pinouts and electrical characteristics to ensure functional compatibility.
