18QHTF21-36.502-PD

Oscillators Overview

The 18QHTF21-36.502-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 36.502 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a power-down standby function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Includes power-down standby capability for energy efficiency
• Utilizes LVCMOS output logic for digital interface compatibility

Oscillators Applications

• General clock signal generation in electronic circuits
• Timing reference for digital systems requiring 36.502 MHz
• Embedded devices utilizing standard XO interfaces

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific temperature range limitations if operating in extreme environments.

Oscillators Selection Notes

Select this component when a precise 36.502 MHz timing source is required in a small form factor. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the power-down feature if battery life or thermal management is a priority. Verify that the 1.8V operating voltage is compatible with the rest of the system components.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies within a standardized 2.0x1.6 mm package. These oscillators are designed for applications needing stable clock signals in space-constrained designs. The 'PD' suffix indicates the inclusion of a power-down control pin.

Oscillators Replacement Considerations

Direct substitutes must match the 36.502 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. Consult manufacturer cross-reference lists for equivalent parts from other suppliers.
