3QHTF57-19.9998-PD

Oscillators Overview

The 3QHTF57-19.9998-PD is a standard XO oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 19.9998 MHz with LVCMOS output levels. The device functions on a 3.3V supply voltage and includes a standby (power down) control feature. It utilizes a 4-SMD, No Lead package configuration for surface mount integration.

Oscillators Feature Summary

• LVCMOS output signal compatibility
• Integrated standby power down control
• Surface mount 4-SMD no lead packaging

Oscillators Applications

• General clock generation in digital systems
• Data communication interface timing
• Microcontroller system clocks

Oscillators Procurement Notes

Verify the exact frequency tolerance and load capacitance requirements against the specific application design before ordering. Confirm that the 4-SMD no lead package dimensions match the PCB footprint constraints. Ensure the 3.3V logic level aligns with the receiving circuit inputs to prevent signal integrity issues or damage.

Oscillators Selection Notes

Select this component when a precise 19.9998 MHz reference is required with low power consumption capabilities. The integrated standby function makes it suitable for battery-operated devices requiring power management. Consider the LVCMOS output swing if interfacing with lower voltage logic families without level shifting.

Oscillators Part Context

This part belongs to the 3QHTF57 series of standard oscillators from Mercury Electronics. The series typically offers various frequencies with consistent electrical characteristics and packaging. The 'PD' suffix indicates the inclusion of a power down pin for energy efficiency.

Oscillators Replacement Considerations

Direct replacements include other 3QHTF57 series variants such as 3QHTF57-20.000-PD if frequency adjustment is acceptable. Cross-reference with similar 4-SMD LVCMOS oscillators from other manufacturers ensuring identical voltage and pinout specifications.
