18QHTF21-60.750-PD

Overview

The 18QHTF21-60.750-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 60.75 MHz and utilizes LVCMOS output logic. The device is designed for low-power applications, featuring a supply voltage of 1.8V and a standby mode for power-down functionality. It is housed in a compact 4-SMD, no-lead package, suitable for surface-mount assembly on printed circuit boards.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated standby mode to reduce power consumption
• Compact 4-SMD no-lead surface-mount package

Applications

• General clock signal generation for embedded systems
• Timing reference for digital communication interfaces
• Power-sensitive portable electronic devices

Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your target platform's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Cross-reference the datasheet for precise electrical characteristics to guarantee signal integrity in high-speed digital environments.

Selection Notes

Select this component when a stable 60.75 MHz clock source is required with minimal power overhead. The LVCMOS output ensures direct interfacing with most microcontrollers and FPGAs without additional level shifting. Consider the 1.8V supply constraint if designing for battery-operated or energy-efficient systems. The small form factor aids in dense board layouts where space is limited.

Part Context

This part belongs to the 18QHTF series of standard oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 'PD' suffix typically indicates the presence of a power-down control feature. This model specifically targets applications needing a precise 60.75 MHz timing reference in a low-profile surface-mount package.

Replacement Considerations

Direct substitutes include other 60.75 MHz LVCMOS oscillators in 4-SMD packages from manufacturers like Epson, NDK, or SiTime. Verify pinout compatibility and electrical specifications such as current consumption and startup time. Ensure the replacement supports the same 1.8V supply and standby functionality to maintain system power management strategies.
