Bi-directional buffer with circuit protection time synchronization
摘要
說明書
For a misconfiguration, scenario 12 represents a scenario where the time synchronization system is unpowered but a signal is received at the SMA port. On the transmit path, isolation circuitry 228 and on the receive path, isolation switch 210 can prevent damage to the time synchronization system by scenario 12.
For a misconfiguration, scenario 17 represents a scenario where a receive path is enabled but there a voltage at the SMA port. This causes a device that can handle 5.5V and translate it to the 3.3V I/O voltage of the system controller 250, which is done with the level shifter 214.
