18QHTF21-19.51594-PD

Oscillators Overview

The 18QHTF21-19.51594-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind., Co., Ltd. It operates at a frequency of 19.51594 MHz with an LVCMOS output signal. The device functions on a 1.8V supply voltage and includes a standby power-down feature. It is housed in a 4-SMD, no lead surface-mount package with dimensions of 2.00mm x 1.60mm.

Oscillators Feature Summary

• LVCMOS output interface for digital logic compatibility
• Integrated standby mode for power management
• Surface-mount construction for automated assembly

Oscillators Applications

• Digital clock signal generation
• Microcontroller system timing

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V operating voltage aligns with the system power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper solder joint integrity during assembly.

Oscillators Selection Notes

Select this component when a precise 19.51594 MHz reference is required for low-voltage digital systems. The choice depends on the necessity for LVCMOS signaling levels and the availability of a 1.8V power supply. Consider the physical size constraints of the application, as the compact 2.0x1.6mm package suits space-sensitive designs requiring surface-mount technology.
