18QHTF21-24.609375-PD

Oscillators Overview

The 18QHTF21-24.609375-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 24.609375 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a standby (power down) function for power management. Frequency stability is specified at ±50ppm. The component is housed in a 4-SMD, No Lead package and supports an operating temperature range of -40°C to 85°C.

Oscillators Feature Summary

• Supports standby mode for power reduction
• Provides LVCMOS output signal compatibility
• Operates within extended industrial temperature ranges

Oscillators Applications

• Digital signal processing systems
• Communication equipment timing
• Embedded control circuits

Oscillators Procurement Notes

Verify the specific suffix PD indicates the standby functionality and LVCMOS output configuration as documented. Confirm the 1.8V supply requirement matches the target circuit design. Ensure the 4-SMD no-lead package dimensions align with the PCB footprint specifications before finalizing procurement orders.

Oscillators Selection Notes

Select this model when a precise 24.609375 MHz clock source is required with low power consumption capabilities. The ±50ppm stability suits general digital applications. Consider the 1.8V supply constraint and ensure the operating temperature range meets environmental requirements for the intended deployment scenario.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies with standardized LVCMOS outputs. The PD suffix denotes the inclusion of a power-down feature, distinguishing it from continuous operation variants within the same family.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with identical pinout and electrical characteristics but different frequencies, such as 18QHTF21-25.000-PD. Verify frequency tolerance and package compatibility when cross-referencing.
