3QHTF22-156.200-PD

Oscillators Overview

The 3QHTF22-156.200-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 156.2 MHz and utilizes LVCMOS output logic levels. The device is designed for a supply voltage of 3.3V and includes a standby or power-down function to manage energy consumption during inactive periods. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.5x2.0 mm, suitable for surface-mount applications.

Oscillators Feature Summary

• Generates a precise 156.2 MHz clock signal using LVCMOS interface
• Operates on a 3.3V power supply with integrated standby capability
• Utilizes a small form-factor 4-SMD no-lead package design

Oscillators Applications

• High-speed digital data transmission systems
• Network communication equipment requiring stable clock sources
• Embedded systems utilizing LVCMOS-compatible processors

Oscillators Procurement Notes

Verify the specific ordering suffix and package variant against the manufacturer's current datasheet before procurement. Ensure that the 3.3V supply requirements and LVCMOS load conditions match the target circuit design. Confirm the presence of the power-down feature if low-power states are required in the final application environment.

Oscillators Selection Notes

Select this component when a 156.2 MHz frequency is strictly required alongside LVCMOS compatibility. The choice depends on the availability of a 3.3V supply rail and the need for a compact 2.5x2.0 mm footprint. Consider the standby functionality if power management during idle states is a critical design parameter for the system.

Oscillators Part Context

This part belongs to the QHTF series of standard oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within a similar small SMD footprint. The 'PD' suffix indicates the inclusion of a power-down control pin, distinguishing it from continuously running variants in the same family.

Oscillators Replacement Considerations

Direct substitutes include other 156.2 MHz LVCMOS oscillators in 4-SMD packages from manufacturers such as Epson, Nihon Dempa Kogyo, or SiTime. Verify pinout compatibility and electrical specifications before swapping. Alternative Mercury parts like the 25QHTF22-156.200-PD differ in voltage and may require circuit adjustments.
