18QHTF21-34.816-PD

Oscillators Overview

The 18QHTF21-34.816-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 34.816 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a power-down function accessible via a standby control pin. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

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

Oscillators Applications

• Portable electronic devices requiring low power consumption
• Communication systems utilizing standard clock signals
• Embedded systems with space-constrained layouts

Oscillators Procurement Notes

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

Oscillators Selection Notes

Choose this component when a precise 34.816 MHz reference is needed alongside strict size limitations. The integrated power-down feature makes it suitable for battery-operated applications where standby current reduction is critical. Verify compatibility with LVCMOS-compatible inputs in the receiving digital logic to ensure signal integrity without additional buffering.

Oscillators Part Context

This model belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies within a standardized 2.0x1.6 mm form factor. These components are designed for high-volume manufacturing environments requiring consistent performance across temperature ranges while maintaining a small physical profile for modern electronics.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical footprints but different frequencies, such as 18QHTF21-51.200-PD or 18QHTF21-6.000-PD, provided the system clock requirement changes. Cross-brand replacements must match the 4-SMD no-lead package, 1.8V supply, and LVCMOS output characteristics.
