18QHTF21-115.330-PD

Overview

The 18QHTF21-115.330-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 115.33 MHz with an LVCMOS output logic level. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a 4-SMD, no-lead package with dimensions of 2.0 x 1.6 mm. The component is supplied in strip packaging format.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby and power-down functionality
• Compact surface-mount design

Applications

• General electronic equipment requiring precise timing
• Communication systems utilizing standard clock signals
• Consumer electronics with space constraints

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required frequency and voltage specifications. Confirm that the 4-SMD no-lead package aligns with PCB layout requirements. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the supplier provides valid documentation matching the manufacturer's official datasheet for quality assurance.

Selection Notes

Select this component when a 115.33 MHz clock signal is required with LVCMOS interface compatibility. Consider the 1.8V supply constraint and the availability of a power-down feature for power-sensitive designs. Evaluate the 2.0x1.6 mm footprint against available board space. Compare against other oscillators in the series for alternative frequencies or package options if needed.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies and output types within a compact SMD form factor. The 'PD' suffix indicates the inclusion of power-down capability, distinguishing it from standard continuous-operation variants in the same family.

Replacement Considerations

Direct substitutes must match the 115.33 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics before substitution. Consult the manufacturer's cross-reference list for approved alternatives.
