Oscillators Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing. Confirm that the AC grade corresponds to the required -20°C to 70°C commercial temperature range for your application environment. Ensure the 1.8V supply rail matches the component's electrical specifications before integration into the design.

Oscillators Selection Notes

Select this model when a 77.76 MHz frequency is required with ±10ppm stability in a 7x5mm package. Consider the AC temperature rating if operation exceeds standard commercial limits or falls below -20°C. Evaluate power consumption requirements against the 31mA active current draw and ensure the LVCMOS/LVTTL output levels match the receiving logic family.

Oscillators Part Context

This component belongs to the SiTime SiT8208 series of ultra-performance MEMS oscillators. The series is designed as a direct replacement for quartz crystals, offering superior reliability metrics such as low failure rates. The specific part number denotes the AC temperature grade, 1.8V supply, and 77.76 MHz frequency output within the standard 4-pin surface mount package options.

Oscillators Replacement Considerations

SiT8208AC-8F-18E-77.760000X serves as a bulk-pack alternative to the T reel variant. Other frequencies in the 1-80 MHz range are available within the same SiT8208 family using different suffix codes.
