18QHTF21-29.1328-PD

Oscillators Overview

The 18QHTF21-29.1328-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 29.1328 MHz with an LVCMOS output logic level. The device supports a supply voltage of 1.8V and features a standby (power down) control function. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0x1.6mm.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated standby control via power down pin
• Compact 4-SMD no lead surface mount package

Oscillators Applications

• Digital signal processing clock sources
• Communication equipment timing references
• Embedded system clock generation

Oscillators Procurement Notes

Verify the specific suffix PD indicates the power down feature against the manufacturer datasheet. Confirm the 1.8V supply requirement matches the target circuit design. Ensure the 4-SMD no lead footprint aligns with the PCB layout specifications before ordering.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standby functionality. The small 2.0x1.6mm package is suitable for space-constrained designs. Verify that the LVCMOS output swing meets the input requirements of the connected load.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies and control options. The PD suffix specifically denotes the power down capability, distinguishing it from OE (enable/disable) variants within the same family.

Oscillators Replacement Considerations

Check for other Mercury parts with the same frequency and package but different control pins. Ensure substitute components support the 1.8V supply and LVCMOS output levels.
