18QHTF21-13.5395-PD

Overview

The 18QHTF21-13.5395-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.5395 MHz with an LVCMOS output logic level. The device requires a 1.8V supply voltage and features a standby mode for power down functionality. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby capability for power management
• Utilizes LVCMOS output interface

Applications

• Battery-powered portable devices
• Compact electronic systems requiring low profile components
• General timing applications in consumer electronics

Procurement Notes

Verify the specific frequency tolerance and operating temperature range against your system requirements before procurement. Ensure that the 1.8V supply voltage aligns with your board's power distribution network. Confirm the 4-SMD no-lead package footprint matches your PCB layout design to avoid assembly issues.

Selection Notes

Select this component when a small form factor is required alongside low-power consumption. The 1.8V specification suits modern low-voltage digital circuits. Consider the LVCMOS output compatibility with your target logic family. The standby feature offers energy savings in idle states compared to always-on oscillators.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on miniature surface-mount oscillators. The series typically includes various frequencies within the same physical footprint. It serves as a timing source for microcontrollers and communication interfaces where space is limited.

Replacement Considerations

Direct substitutes must match the 13.5395 MHz frequency, 1.8V supply, and 2.0x1.6mm package. Verify pinout compatibility and output drive strength. Check if alternative brands offer equivalent jitter performance and temperature stability for your application.
