18QHTF21-10.83322-PD

Overview

The 18QHTF21-10.83322-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 10.83322 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. It features a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The component supports a standby or power-down mode to reduce energy consumption when not in active use.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby functionality for power management
• Utilizes quartz-based frequency stability

Applications

• General clock signal generation in electronic circuits
• Timing reference for low-voltage digital systems
• Embedded system clock sources

Procurement Notes

Verify the exact frequency tolerance and load capacitance requirements against the specific application design before procurement. Confirm that the 1.8V supply voltage aligns with the target circuit's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a precise 10.83322 MHz timing source is required for 1.8V logic families. Consider the small 2.0x1.6mm form factor for space-constrained designs. Evaluate the need for standby capabilities if power efficiency is a critical design parameter compared to continuous operation oscillators.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies within a standardized low-profile package. The 'PD' suffix likely indicates a specific tape-and-reel packaging option or variant configuration provided by the manufacturer for automated assembly processes.

Replacement Considerations

Direct substitutes must match the 10.83322 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter if available in official datasheets.
