18QHTF21-24.4196-PD

Oscillators Overview

The 18QHTF21-24.4196-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 24.4196 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a power-down function via a standby control pin. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby mode for power management
• Provides LVCMOS digital output signals
• Utilizes a small surface-mount footprint

Oscillators Applications

• General clock signal generation
• Digital circuit timing references
• Embedded system clock sources
• Portable electronic devices

Oscillators Procurement Notes

Verify the specific frequency suffix matches the design requirement of 24.4196 MHz. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the LVCMOS output compatibility is suitable for the receiving logic inputs. Check that the 4-SMD package size fits within the available PCB area constraints.

Oscillators Selection Notes

Select this component when a precise 24.4196 MHz reference is required in space-constrained designs. The choice is driven by the need for low power consumption due to the 1.8V operation and standby capability. Consider the LVCMOS interface for direct connection to standard digital logic without additional level shifting.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on miniature oscillators. The series typically offers various frequencies and voltages. The 'PD' suffix indicates the inclusion of a power-down feature, distinguishing it from continuous-output variants within the same physical package family.

Oscillators Replacement Considerations

Direct substitutes must match the 24.4196 MHz frequency, 1.8V voltage, LVCMOS output, and 2.0x1.6mm package. Verify pinout compatibility before replacement.
