Procurement Notes
Verify the specific suffix (OE) against the manufacturer's current datasheet to confirm exact electrical tolerances and pinout configurations. Ensure the required operating temperature range aligns with the application environment. Confirm that the 1.8V supply voltage matches the target system's power rails before integration.
Selection Notes
Select this component when a precise 75.355 MHz clock source is required with low voltage operation. The LVCMOS output is suitable for direct interfacing with standard CMOS logic families. Consider the small 2.0x1.6mm footprint for space-constrained designs requiring reliable quartz stability.
Part Context
This oscillator belongs to Mercury's QuikXO series, which focuses on rapid delivery of custom and standard frequency solutions. The brand has been active in the crystal industry since 1973, specializing in frequency control products. This specific model represents a standard frequency variant within their SMD oscillator portfolio.
Replacement Considerations
The 18QHTF21-75.355-PD is listed as an equivalent or alternate part number for this frequency and package type. Verify compatibility with the PD suffix variant regarding electrical specifications and mechanical mounting requirements before substitution.
