18QHTF21-88.000-PD

Overview

The 18QHTF21-88.000-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 88 MHz and utilizes LVCMOS output logic levels. The device is designed for low voltage applications, specifically requiring a 1.8V supply voltage. It features a power-down capability to reduce consumption when not in use. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm, suitable for surface mount assembly.

Feature Summary

• Supports LVCMOS output interface for digital compatibility
• Includes standby mode for power management
• Utilizes small form factor SMD packaging

Applications

• Consumer electronics timing circuits
• Portable device clock generation
• Embedded system synchronization

Procurement Notes

Verify the specific ordering suffix PD against the manufacturer's current datasheet to ensure correct pinout and electrical characteristics. Confirm that the 1.8V supply requirement aligns with your system design before procurement. Check for any recent revisions to the mechanical outline drawing to ensure board layout compatibility.

Selection Notes

Select this component when a precise 88 MHz reference is required in space-constrained designs. Ensure the target circuit supports the 1.8V operating voltage range. Consider the power-down feature if energy efficiency is critical for the application. Verify load capacitance requirements match the connected microcontroller or FPGA inputs.

Part Context

This part belongs to the QHTF series of high-frequency oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within a standardized 2.0x1.6 mm footprint. It serves as a timing source for systems needing stable clock signals without the complexity of external resonators.

Replacement Considerations

Direct substitutes must match the 88 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Cross-reference with other Mercury models like the 3QHTF21 series only if voltage tolerance allows. Verify pin-to-pin compatibility before replacing.
