Car radio tuner front-end for digital IF
10. Limiting values
[1] To avoid damages and wrong operation it is necessary to keep all 8.5 V supply voltages at a higher level than any 5 V supply voltage.
This is also necessary during power-on and power-down sequences. Precautions have to be provided in such a way that interferences
can not pull down the 8.5 V supply below the 5 V supply.
[2] Machine model (R = 0 Ω, C = 200 pF).
[3] Human body model (R = 1.5 kΩ, C = 100 pF).
