18QHTF21-28.160-PD

Oscillators Overview

The 18QHTF21-28.160-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a frequency of 28.16 MHz. It utilizes LVCMOS output logic and functions with a supply voltage of 1.8V. The device features a power-down capability via a standby mode. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby mode for power-down functionality
• Utilizes a small form factor 4-SMD no lead package

Oscillators Applications

• General clock signal generation in electronic circuits
• Timing reference for digital systems requiring 28.16 MHz
• Embedded devices utilizing low voltage logic interfaces

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD package footprint matches the PCB layout constraints. Check for any specific RoHS compliance documentation if required by project regulations.

Oscillators Selection Notes

Select this component when a precise 28.16 MHz timing source is required within a low-voltage 1.8V environment. The choice is driven by the need for LVCMOS compatibility and space-constrained applications due to the 2.0x1.6 mm package size. Consider the power-down feature if energy efficiency during idle states is a priority for the system architecture.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides standard clock oscillators. The manufacturer has a history of producing quartz crystals and frequency control products since 1973. This specific model represents their capability in manufacturing surface-mount oscillators with defined electrical characteristics and physical dimensions.

Oscillators Replacement Considerations

Direct substitutes must match the 28.16 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical specifications such as phase noise and jitter if available in official datasheets.
