Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against the target application specifications before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD footprint matches the PCB layout constraints. Cross-reference the manufacturer's latest datasheet to confirm current production status and environmental compliance certifications.
Selection Notes
Select this component when a precise 61.250 MHz clock source is required with low profile packaging. The LVCMOS output is suitable for standard digital logic families operating at 1.8V. Consider the enable pin feature if power management or clock gating is necessary within the design. Verify thermal performance and stability requirements against the standard specification range provided in the official documentation.
Part Context
This oscillator belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, which offers various frequencies within a standardized small outline package. The series provides consistent form factors across different frequency options, facilitating board space optimization. Mercury Electronics specializes in quartz-based frequency control products, including crystals and oscillators, serving global electronics manufacturing needs.
Replacement Considerations
Direct substitutes include other 18QHTF21 series variants with identical pinouts but different frequencies, such as 18QHTF21-37.200-OE or 18QHTF21-59.648-OE, provided the frequency difference is acceptable. Ensure any replacement maintains the same 1.8V supply voltage and LVCMOS output characteristics.
