18QHTF21-33.280-PD

Oscillators Overview

The 18QHTF21-33.280-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a nominal frequency of 33.28 MHz and utilizes LVCMOS output logic. The device is designed for low-power applications, featuring a supply voltage of 1.8V and a standby power-down mode. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0 x 1.6 mm. This component serves as a precise clock source for digital circuits requiring stable timing signals.

Oscillators Feature Summary

• Supports LVCMOS output logic for direct interface with digital systems
• Includes standby power-down functionality to reduce energy consumption
• Utilizes quartz crystal technology for high frequency stability

Oscillators Applications

• Digital signal processing equipment
• Communication modules requiring precise clocking
• Embedded systems with low power constraints

Oscillators Procurement Notes

Verify the specific ordering suffix and frequency tolerance against project requirements. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD package footprint matches the PCB design guidelines. Check for any specific environmental operating temperature ranges required by the application.

Oscillators Selection Notes

Select this model when a 33.28 MHz clock signal is necessary for data transmission standards. Consider the 1.8V operation if the system architecture prioritizes low voltage efficiency. The small 2.0x1.6 mm form factor is suitable for space-constrained designs. Evaluate the need for standby modes if power management is critical.

Oscillators Part Context

This part belongs to the Mercury Electronics SMD oscillator series, which includes various frequencies and packages. The 'PD' suffix typically indicates the power-down feature. Mercury Electronics specializes in quartz crystals and oscillators, offering a range of frequency control products for industrial and consumer electronics markets.

Oscillators Replacement Considerations

Direct substitutes must match the 33.28 MHz frequency, LVCMOS output, and 1.8V supply. Compatible alternatives from other manufacturers should offer similar 4-SMD no-lead packaging. Verify pinout compatibility and thermal characteristics before substitution.
