• Embedded controller clock sources

Procurement Notes

Verify the specific operating temperature range 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 no-lead package footprint matches your PCB layout constraints to prevent assembly issues during manufacturing.

Selection Notes

Select this component when a precise 65.48175 MHz clock source is required for low-voltage digital circuits. The integrated enable feature makes it suitable for battery-powered or power-sensitive applications. Consider the small 5.0x3.2mm form factor for space-constrained designs requiring standard LVCMOS interfaces.

Part Context

This oscillator belongs to the MODbox Series from Mercury Electronics, a supplier specializing in quartz crystals and oscillators since 1973. The series offers various frequencies and packages, providing standardized timing solutions for consumer electronics and industrial equipment. The company is based in Taiwan and focuses on frequency-control products.

Replacement Considerations

Direct substitutes must match the 65.48175 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify equivalent jitter specifications and enable functionality. Cross-reference with other manufacturers offering identical electrical parameters and mechanical dimensions to ensure pin-to-pin compatibility.
