18QHTF21-26.8436-PD

Oscillators Overview

The 18QHTF21-26.8436-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 26.8436 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a Standby (Power Down) control function to manage power consumption. 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) mode for energy efficiency
• Utilizes LVCMOS output logic interface
• Compact 4-SMD No Lead surface mount package

Oscillators Applications

• General clock signal generation
• Embedded system timing references
• Portable electronic devices requiring low power

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Ensure that the 1.8V supply voltage aligns with the system's power rails. Confirm that the LVCMOS output levels are compatible with the receiving logic inputs to prevent signal integrity issues or damage.

Oscillators Selection Notes

Select this component when a precise 26.8436 MHz reference is required in space-constrained applications. The choice depends on the necessity for a 1.8V operating voltage and the availability of a standby control pin. Evaluate the thermal performance and size constraints of the 2.0x1.6mm package relative to the PCB layout.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies within a small form factor. The 'PD' suffix indicates the inclusion of a power-down feature, distinguishing it from standard continuous-operation variants within the same physical footprint.

Oscillators Replacement Considerations

Direct replacements must match the 26.8436 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify that substitute components support the Standby function if power management is critical to the application design.
