1. SIT8208AI-G1-33E-62.500000Y Substitution Conclusion
This model can serve as a direct replacement for the original part, as all key parameters are identical: both operate at 62.5 MHz, with a 3.3V supply, LVCMOS/LVTTL outputs, Enable/Disable functionality, and identical package dimensions. The primary improvement is in frequency stability, which has been enhanced from ±25ppm to ±20ppm. This provides higher clock accuracy under variations in temperature and voltage, representing a performance upgrade without compatibility issues. However, it should be noted that if the system timing tolerance is very relaxed (e.g., only ±50ppm is required), this tighter specification may lead to unnecessary cost increase.
2. SIT8208AI-G2-25E-62.500000T Substitution Conclusion
This model is not a direct substitute for the original part due to a supply voltage mismatch: it operates at 2.5V, whereas the original requires 3.3V. Although frequency, package, output type, and other functions are the same, the voltage difference will cause signal level incompatibility. Using a 2.5V device in a 3.3V system may result in insufficient output levels to drive downstream circuitry. Forced substitution could also lead to device damage or timing errors due to voltage tolerance limits. Replacement is only feasible if the target system supply voltage matches 2.5V; otherwise, a power supply redesign or level‑shifting circuit is required.
