18QHTF21-93.300-PD

Overview

The 18QHTF21-93.300-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 93.3 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. It features a standby or power-down function to manage energy consumption when not in active 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 in space-constrained electronic designs.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby and power-down functionality for power management
• Utilizes a compact 4-SMD no-lead surface mount package

Applications

• General clock signal generation in embedded systems
• Timing reference for digital communication interfaces
• Clock source for microprocessors and FPGAs operating at 1.8V

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure the correct pinout and electrical specifications. Confirm that the 1.8V supply requirement aligns with the target system design. Check for any recent updates to the datasheet regarding thermal characteristics or reliability standards before finalizing procurement.

Selection Notes

Select this component when a precise 93.3 MHz timing source is required for 1.8V logic circuits. The choice is driven by the need for a small footprint provided by the 2.0x1.6 mm package. Ensure the application does not require frequency tuning, as this is a standard XO without external control capabilities.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies within the same physical form factor. This specific model provides a high-frequency option suitable for modern high-speed digital applications requiring stable clock signals.

Replacement Considerations

Direct substitutes must match the 93.3 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pin compatibility and electrical parameters before replacing.
