18QHTF21-29.790-PD

Oscillators Overview

The 18QHTF21-29.790-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 29.79 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby or power-down function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• Supports standby mode via power-down control
• Utilizes LVCMOS output logic interface
• Compact surface-mount form factor

Oscillators Applications

• General clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 2.0x1.6 mm SMD package dimensions to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a precise 29.79 MHz clock signal. The choice is appropriate for space-constrained designs due to the small 2.0x1.6 mm package. Consider the power-down feature if energy efficiency during idle states is a critical design parameter for the electronic system.

Oscillators Part Context

This model belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz frequency control products. The series includes various oscillators such as TCXOs and VCXOs. This specific part represents a standard XO variant optimized for low voltage and small size applications within the manufacturer's portfolio.

Oscillators Replacement Considerations

Direct substitutes include other variants within the same series with different frequencies, such as 18QHTF21-51.200-PD or 18QHTF21-38.680-PD, provided the frequency difference is acceptable for the application.
