Procurement Notes

Verify the specific ordering suffix to confirm the exact output type and tolerance requirements. Ensure the selected variant matches the required operating temperature range and load capacitance specifications for the target application. Cross-reference the manufacturer datasheet for pinout details and recommended soldering profiles to guarantee reliable assembly and long-term performance stability.

Selection Notes

Select this component when a 59.407 MHz frequency is strictly required for system synchronization. Consider the 1.8V supply constraint and LVCMOS compatibility with downstream logic levels. Evaluate the 2.0x1.6 mm footprint against available PCB space. Confirm that the enable/disable feature aligns with system power sequencing requirements and standby current limitations.

Part Context

This oscillator belongs to the Mercury Electronics XO series, which focuses on quartz-based timing solutions. The brand specializes in frequency control products including crystals, TCXOs, and VCTCXOs.
