18QHTF21-23.5008-PD

Oscillators Overview

The 18QHTF21-23.5008-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 23.5008 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features a power-down standby function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm. This component is designed for applications requiring precise timing signals within low-voltage digital systems.

Oscillators Feature Summary

• Supports LVCMOS output logic for standard digital interfacing
• Includes standby mode capability via power-down control
• Utilizes a small form factor SMD package for space-constrained designs

Oscillators Applications

• General purpose clock signal generation
• Low voltage digital circuit timing
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 2.0x1.6mm 4-SMD no lead package dimensions to guarantee proper mechanical fit and electrical connection during assembly.

Oscillators Selection Notes

Select this oscillator when a 23.5008 MHz frequency is required with LVCMOS outputs. Consider the 1.8V operating voltage constraint and the need for a power-down feature. Evaluate the physical size constraints of the 2.0x1.6mm package against available board space. Compare performance needs against other frequencies in the 18QHTF21 series if alternative timing is acceptable.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various standard frequencies. The series typically provides LVCMOS outputs and supports low voltage operation. The suffix PD indicates the inclusion of a power-down or standby function. Other variants in this line share similar packaging and electrical characteristics but differ in nominal frequency.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with identical pinout and package, such as 18QHTF21-21.500-PD or 18QHTF21-51.200-PD, provided the frequency difference is acceptable. Verify that any replacement maintains the 1.8V supply requirement and LVCMOS output type.
