18QHTF21-14.296875-PD

Oscillators Overview

The 18QHTF21-14.296875-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 14.296875 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. A key functional characteristic is the inclusion of a standby or power-down mode capability, allowing for energy management during inactive periods. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm, suitable for surface-mount assembly in space-constrained electronic designs.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Features standby or power-down mode for power efficiency
• Compact 4-SMD no-lead surface mount package design

Oscillators Applications

• Digital signal processing systems requiring precise clock timing
• Communication equipment utilizing standard frequency references

Oscillators Procurement Notes

Verify the specific ordering suffix to ensure the correct package type and electrical specifications match the design requirements. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the LVCMOS output level is compatible with the receiving logic inputs. Check for any specific temperature range requirements if operating in extreme environments.

Oscillators Selection Notes

Select this component when a stable 14.296875 MHz reference is required for LVCMOS-compatible circuits. The choice is driven by the need for a small form factor and low-power operation due to the standby feature. Consider the 1.8V supply requirement against available power sources. Evaluate the thermal performance if the application involves high ambient temperatures.
