18QHTF21-33.200-PD

Oscillators Overview

The 18QHTF21-33.200-PD is a 33.2 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It utilizes LVCMOS output logic and operates at a supply voltage of 1.8V. The component features a Standby (Power Down) control function to manage power consumption. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. This surface-mount device is designed for applications requiring precise timing signals within low-voltage digital systems.

Oscillators Feature Summary

• Supports Low Voltage CMOS (LVCMOS) output logic levels
• Includes standby mode capability for power management
• Utilizes a compact 4-SMD no-lead surface mount package

Oscillators Applications

• Digital signal processing circuits
• Communication equipment timing references
• Embedded system clock generation

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the PCB footprint matches the 2.0x1.6 mm 4-SMD no-lead package dimensions to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-profile, low-voltage oscillator is required for space-constrained designs. The LVCMOS interface ensures compatibility with standard digital logic families operating at 1.8V. Consider the standby feature if power efficiency is critical. Validate that the 33.2 MHz frequency meets the system's clocking needs without requiring external dividers or multipliers.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a small form factor. The 'PD' suffix indicates the presence of a power-down pin or control functionality. Similar parts in this series include variants with different frequencies such as 33.000 MHz or 51.200 MHz, all sharing the same physical package and electrical characteristics.

Oscillators Replacement Considerations

Direct replacements must match the 33.2 MHz frequency, 1.8V operation, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility, specifically the location of the enable/standby pin, to ensure seamless integration into existing PCB layouts without redesign.
