18QHTF21-13.5485-PD

Overview

The 18QHTF21-13.5485-PD is a fixed-frequency crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a nominal frequency of 13.5485 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. It features a power-down function to reduce energy consumption when not in use. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm, suitable for space-constrained surface-mount designs.

Feature Summary

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

Applications

• General purpose clock signal generation in embedded systems
• Timing reference for low-voltage digital circuits
• Consumer electronics requiring compact oscillator solutions

Procurement Notes

Verify the specific frequency tolerance and operating temperature range requirements against the official datasheet before procurement. Ensure that the 1.8V supply voltage aligns with the target system's power architecture. Confirm that the 4-SMD no-lead package footprint matches the PCB layout constraints. Check for any specific handling instructions related to the surface-mount technology used in this component series.

Selection Notes

Select this component when a precise 13.5485 MHz timing source is required for LVCMOS-compatible logic families. The choice is driven by the need for a low-profile 2.0x1.6mm package and integrated power management capabilities. Consider the 1.8V operating voltage constraint relative to other available supply options in the product line. Evaluate the trade-off between size and performance metrics provided in the manufacturer's specifications.
