Oscillators Procurement Notes

Verify the specific suffix (OE) against official datasheets to confirm the enable/disable feature is active. Ensure the operating temperature range meets application requirements. Cross-reference the 2.72 MHz frequency tolerance specifications with design constraints. Confirm the 1.8V supply voltage aligns with the target system's power rails before finalizing procurement.

Oscillators Selection Notes

Select this component when a precise 2.72 MHz reference is required for LVCMOS-compatible logic families. The 1.8V operation makes it suitable for modern low-voltage digital systems. The enable/disable pin allows for dynamic power saving, which is critical for battery-operated devices. The small 2.0x1.6 mm footprint aids in high-density PCB layouts where space is limited.

Oscillators Part Context

Mercury Electronic Ind. Co., Ltd. specializes in frequency control products, including quartz crystals and oscillators. This model belongs to their XO series, designed for standard timing applications.
