18QHTF21-61.965-OE

Overview

The 18QHTF21-61.965-OE is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 61.965 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• Provides stable clock signal generation at 61.965 MHz
• Supports low-voltage operation at 1.8V
• Includes enable/disable functionality for power control

Applications

• General-purpose digital circuit timing
• Embedded system clock sources
• Communication interface synchronization

Procurement Notes

Verify the specific suffix 'OE' indicates the enable/disable feature as documented. Confirm the operating temperature range and load capacitance requirements against the official datasheet before integration. Ensure compatibility with the target board's voltage levels and footprint dimensions.

Selection Notes

Select this component when a 61.965 MHz clock source with LVCMOS output is required. Consider the 1.8V supply constraint and the need for active power management via the enable pin. Evaluate the 4-SMD package size against available PCB space constraints.

Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies and output types. The 'OE' suffix typically denotes the inclusion of an enable/disable control line, distinguishing it from constant-output variants like the '-PD' suffix which may indicate standby or power-down modes.

Replacement Considerations

Direct substitutes include other 61.965 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation and enable pins. Verify pinout compatibility and electrical specifications such as jitter and stability before substitution.
