18QHTF21-8.200-PD

Overview

The 18QHTF21-8.200-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 8.2 MHz and utilizes LVCMOS output logic. The device is designed for low-power applications, featuring a supply voltage of 1.8V and a standby power-down mode. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Supports low-voltage operation at 1.8V with integrated power-down functionality
• Delivers standard LVCMOS output signals for digital interface compatibility
• Utilizes a miniature 4-SMD no-lead surface-mount package design

Applications

• Portable electronic devices requiring low power consumption
• Digital signal processing circuits
• Communication equipment clock sources

Procurement Notes

Verify the specific ordering suffix to ensure the correct package variant and tolerance specifications match the design requirements. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Check for RoHS compliance status if environmental regulations apply to the end product. Ensure the operating temperature range meets the intended application environment constraints.

Selection Notes

Select this component when a precise 8.2 MHz reference is required for LVCMOS-compatible digital logic. The choice is driven by the need for a small footprint and low standby current capabilities. Consider the 1.8V supply constraint and the availability of the specific 4-SMD package form factor for PCB layout optimization.

Part Context

This part belongs to the Mercury Electronics XO series, which provides frequency control solutions. The manufacturer has decades of experience in quartz crystal production. This specific model represents a standard oscillator variant within their portfolio, distinct from TCXO or VCXO types.

Replacement Considerations

Direct substitutes must match the 8.2 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package dimensions. Verify pinout compatibility and electrical characteristics before substitution.
