18QHTF21-24.832-PD

Oscillators Overview

The 18QHTF21-24.832-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 24.832 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and 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 2.0 x 1.6 mm. This component serves as an active clock source for digital circuits requiring precise timing signals.

Oscillators Feature Summary

• Supports Standby (Power Down) mode for energy efficiency
• Utilizes LVCMOS output logic for digital interface compatibility
• Compact 4-SMD No Lead surface-mount package design

Oscillators Applications

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

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 24.832 MHz application. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the LVCMOS output logic is compatible with the receiving input pins. Check that the 4-SMD No Lead package footprint fits the PCB layout constraints. Validate the operating temperature range against environmental requirements.

Oscillators Selection Notes

Select this model when a low-voltage 1.8V clock source is required. Consider the small 2.0x1.6 mm footprint for space-constrained designs. Choose LVCMOS logic if interfacing with standard CMOS-compatible inputs. Evaluate the need for a standby pin if power management is critical. Compare against other frequencies in the 18QHTF21 series if different clock speeds are needed.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies within a standardized 1.8V LVCMOS format. The 'PD' suffix indicates the inclusion of a Power Down feature. The manufacturer has extensive experience in quartz crystal production since 1973.

Oscillators Replacement Considerations

Direct substitutes must match the 24.832 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify pinout compatibility before replacement. Other Mercury Electronics models in the same series may differ only in frequency.
