Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Request the official datasheet from Mercury Electronic Ind. Co., Ltd. to validate electrical characteristics and reliability standards for your specific application environment.

Oscillators Selection Notes

Select this component when a precise 18.8696 MHz clock source is required with low power consumption features. The LVCMOS output is suitable for direct interfacing with digital logic families operating at 1.8V. Consider the small 2.0x1.6mm package size for space-constrained designs. Evaluate the standby function if power efficiency during idle states is a critical design parameter.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronic Ind. Co., Ltd. The manufacturer has over 50 years of experience in quartz crystal production. The series typically offers various frequency options within a standardized small outline package format, providing reliable timing solutions for consumer and industrial electronics.

Oscillators Replacement Considerations

Direct substitutes must match the 18.8696 MHz frequency, 1.8V LVCMOS output, and 4-SMD 2.0x1.6mm package dimensions. Verify pin compatibility and electrical specifications with alternative manufacturers such as Epson or SiTime if Mercury parts are unavailable. Ensure the replacement supports the same standby functionality.
