Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 2.0x1.6mm 4-SMD no-lead package specifications to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-profile oscillator with enable capabilities is required for 1.8V logic systems. Consider the operating temperature range and stability requirements relative to the application environment. Evaluate the need for spread spectrum or differential outputs if noise immunity is critical, as this model provides single-ended LVCMOS signals.

Oscillators Part Context

This part belongs to the H21 series of SMD oscillators from Mercury Electronics. The series focuses on small form factor solutions for portable and industrial electronics. Mercury Electronics specializes in quartz crystals and frequency control products, leveraging decades of manufacturing expertise to produce reliable timing components for various global markets.

Oscillators Replacement Considerations

Direct substitutes must match the 17.734476 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as current consumption and startup time. Cross-reference with other manufacturers offering equivalent low-profile oscillators with enable pins.
