18QHTF21-60.2353-PD

Overview

The 18QHTF21-60.2353-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 60.2353 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features a standby or power-down function 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-power electronic systems.

Feature Summary

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

Applications

• Digital signal processing circuits
• Communication equipment timing references
• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD package footprint matches your PCB layout constraints. Check for any specific handling instructions related to the no-lead package type during assembly.

Selection Notes

Select this model when a 60.2353 MHz clock signal is required with LVCMOS outputs. Consider the 1.8V operating voltage for compatibility with low-voltage logic families. The small 2.0x1.6 mm package is suitable for space-constrained designs. Evaluate the need for standby functionality if power efficiency is a priority in the target application environment.

Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS output and 1.8V operation. The 'PD' suffix typically indicates the inclusion of a power-down feature. These components are part of Mercury's broader portfolio of quartz-based frequency control products.

Replacement Considerations

Direct substitutes must match the 60.2353 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical specifications such as rise/fall times and duty cycle. Cross-reference with other manufacturers offering similar low-profile oscillators with identical form factors and electrical characteristics.
