1. SIT8208AI-G2-28E-62.500000Y Substitution Conclusion
This device is fully compatible with the original model in terms of package, frequency, output type, and functionality. However, the core difference lies in its operating voltage of 2.8V, compared to 2.5V for the original part. If the existing system power supply is designed exclusively for 2.5V, direct substitution may result in clock signal level mismatch or operational instability. It is essential to verify that downstream receiver devices are compatible with 2.8V LVCMOS/LVTTL input levels. Conversely, if the system power rail can be adapted to 2.8V, other electrical characteristics—such as supply current and enable current—are well-matched, making the device a suitable replacement.
2. SIT8208AI-GF-25E-62.500000T Substitution Conclusion
This model is identical to the original in package, frequency, output type, functionality, and operating voltage (2.5V). The key improvement is its enhanced frequency stability of ±10ppm, compared to ±25ppm for the original. The higher frequency accuracy makes it particularly advantageous for timing-critical applications, such as high-speed communication or precision synchronization, with no electrical compatibility risks. Therefore, it can directly replace the original model with a performance upgrade. Note that the suffix “T” versus “Y” may indicate differences in temperature range or packaging format; it is recommended to review the datasheet to confirm that these details meet production requirements.
