18QHTF21-35.328-PD

Oscillators Overview

The 18QHTF21-35.328-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 35.328 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and features a standby (power down) control mode. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports standby power down functionality for energy management
• Utilizes LVCMOS output logic for digital interfacing
• Compact surface-mount package design

Oscillators Applications

• General clock signal generation
• Digital system timing references
• Embedded electronics applications

Oscillators Procurement Notes

Verify the specific ordering suffix to ensure the correct pinout and electrical characteristics match the target design requirements. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD no lead package footprint corresponds to the PCB layout specifications before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a precise 35.328 MHz reference frequency. The inclusion of a power-down feature makes it suitable for battery-operated or power-sensitive designs. Consider the small 2.0x1.6mm form factor for space-constrained board layouts requiring standard LVCMOS outputs.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in frequency control products. The series typically offers various frequencies within a standardized small outline package format. Mercury Electronics has established itself as a manufacturer of crystal components since 1973, focusing on Taiwan-based production.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical 35.328 MHz frequencies but different suffixes such as -OE for enable/disable control instead of power down. Cross-reference with other manufacturers offering 2.0x1.6mm LVCMOS oscillators at 1.8V if Mercury stock is unavailable.
