18QHTF21-89.088-PD

Overview

The 18QHTF21-89.088-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 89.088 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and supports a standby or power-down mode for energy management. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0 x 1.6 mm. This component is designed for applications requiring precise timing signals within low-voltage digital systems.

Feature Summary

• Supports low-voltage operation at 1.8V with LVCMOS output compatibility
• Includes standby and power-down functionality for efficient power management
• Utilizes a compact 4-SMD no-lead surface-mount package design

Applications

• Digital signal processing circuits requiring precise clock synchronization
• Communication equipment utilizing standard LVCMOS interfaces
• Portable electronic devices necessitating low-power consumption modes

Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply rail stability meets the oscillator's jitter specifications. Ensure the PCB layout accommodates the 2.0x1.6mm footprint and no-lead soldering profile to guarantee reliable electrical contact and thermal performance during assembly.

Selection Notes

Select this model when a fixed 89.088 MHz frequency is required for LVCMOS-compatible digital logic. Consider the 1.8V supply constraint and the availability of standby control signals in your system architecture. Evaluate the physical space constraints to ensure the 4-SMD no-lead package fits within the designated area on the printed circuit board without interfering with adjacent components.

Part Context

This part belongs to the QHTF series of standard crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options, including 2.5V variants like the 25QHTF57 series. The 'PD' suffix indicates the inclusion of power-down capabilities, distinguishing it from basic continuous-operation models within the manufacturer's portfolio.

Replacement Considerations

Direct substitutes must match the 89.088 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and electrical characteristics such as jitter and phase noise. Cross-reference with other manufacturers offering equivalent surface-mount oscillators if Mercury Electronics inventory is unavailable.
