18QHTF21-101.6064-PD

Overview

The 18QHTF21-101.6064-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 101.6064 MHz and utilizes LVCMOS output logic for digital signal interfacing. The device requires a supply voltage of 1.8V and features a standby mode for power 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 space-constrained electronic systems.

Feature Summary

• Supports low-voltage operation at 1.8V with integrated standby functionality
• Delivers standard LVCMOS output signals for direct digital interface compatibility
• Utilizes a surface-mount 4-SMD no-lead package for automated assembly

Applications

• High-speed data communication interfaces requiring precise clock synchronization
• Embedded systems utilizing microcontrollers or FPGAs needing stable timing references
• Consumer electronics devices with strict size limitations for internal circuitry

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before ordering. Confirm that the 1.8V supply rail is stable and within the operational limits specified in the official datasheet. Ensure PCB layout guidelines for the 4-SMD package are followed to maintain signal integrity and thermal performance during production.

Selection Notes

Select this model when a 101.6064 MHz clock source is required with LVCMOS compatibility. Consider the 1.8V operating voltage constraint and the physical footprint of the 2.0x1.6mm package. Evaluate if the standard frequency stability meets the application's jitter and phase noise requirements compared to other available options in the series.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies including 51.2 MHz and 68.665 MHz, all sharing similar packaging and electrical characteristics. These components are engineered for reliability in industrial and commercial environments, providing consistent performance across temperature variations.

Replacement Considerations

Direct substitutes include the 18QHTF21-51.200-PD and 18QHTF21-68.665-PD from the same manufacturer, provided the frequency difference is acceptable for the target application. Cross-brand replacements require careful verification of pinout compatibility, voltage levels, and output logic types to ensure functional equivalence.
