Procurement Notes

Verify the exact part number suffix against official Mercury Electronics documentation to ensure correct frequency and package configuration. Confirm that the LVCMOS output type matches the target circuit requirements. Check for any specific handling instructions related to the 4-SMD no lead package during assembly. Ensure the 1.8V supply voltage aligns with the system design specifications before procurement.

Selection Notes

Select this component when a precise 13.503 MHz clock source is required for low-voltage digital circuits. The LVCMOS output is suitable for direct interfacing with standard logic families. Consider the enable/disable feature if power management is a priority. The small form factor makes it appropriate for space-constrained designs. Verify temperature range requirements against the datasheet specifications.

Part Context

This oscillator belongs to the standard XO series from Mercury Electronics, which specializes in quartz frequency control products. The company has extensive experience in manufacturing crystals and oscillators since 1973. This specific model represents a common solution for providing stable clock signals in modern electronic devices requiring low power and small footprint.

Replacement Considerations

Direct substitutes must match the 13.503 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD no lead package. Cross-reference with other Mercury Electronics models in the H21 or similar series if available. Ensure pinout compatibility and electrical characteristics are identical before substitution.
