18QHTF21-29.900-PD

Oscillators Overview

The 18QHTF21-29.900-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 29.9 MHz with an LVCMOS output signal type. The device functions at a supply voltage of 1.8V and includes a standby or power-down control feature for enable/disable functionality. It is housed in a compact 4-SMD, no lead package suitable for surface mount applications.

Oscillators Feature Summary

• Provides stable 29.9 MHz clock signals via LVCMOS interface
• Supports low-voltage operation at 1.8V
• Integrates standby mode for power management

Oscillators Applications

• General-purpose digital circuit timing
• Embedded system clock generation
• Communication module synchronization

Oscillators Procurement Notes

Verify the specific ordering suffix PD against official Mercury Electronics documentation to confirm the exact electrical characteristics and package variant. Ensure compatibility with the target board's voltage levels and footprint requirements before procurement.

Oscillators Selection Notes

Select this component when a 29.9 MHz frequency is required with LVCMOS outputs. Consider the 1.8V operating voltage and the need for standby control features. Evaluate the 4-SMD package size against available PCB space constraints.

Oscillators Part Context

This part belongs to the 18QHTF series of standard oscillators from Mercury Electronics. Similar models in this family include variants with different frequencies such as 51.2 MHz or 8.0 MHz, often sharing similar package types and voltage specifications but differing in output frequency and control pin configurations.

Oscillators Replacement Considerations

Direct substitutes may include other 29.9 MHz XO components with matching 1.8V LVCMOS outputs and 4-SMD packages. Verify pinout compatibility and electrical parameters against original datasheets before substitution.
