JT AG socket interface with DSP chips Distance: JTAG signals in order to guarantee uninterrupted, need to pay attention to the distance between the two is not more than 6 inches (15 A 24 centimeters), more than this distance, we need to increase the buffer between chips. This design was used as a buffer chip 244, but its not because the distance between devices is too long, but taking into account the work in the simulator 5V Voltage, DSP-pin to 3.3V, in order to conduct the compatibility level of the voltage conversion function.
