Embodiments of bidirectional repeaters and communications systems are disclosed. In an embodiment, a bidirectional repeater includes a digital state machine configured to control the bidirectional repeater to operate under a functional mode or under a bypass mode and a bypass mode driver configured to automatically detect a direction of signal through input/output (I/O) terminals of the bidirectional repeater and to allow a signal to pass through the bidirectional repeater based on the direction of signal under the bypass mode.

Bidirectional bypass mode

Various embodiments relate to an end of packet (EOP) circuit, including: a reset pulse generator circuit configured to generate a reset pulse when a input signal transitions to a new value; an analog counter circuit configured to receive a squelch signal to start the counter and to receive the reset pulse to reset the counter; and an EOP detector circuit configured to produce a signal indicative that the input signal is an EOP signal based upon an output of the analog counter circuit.

End of packet detection

Various embodiments relate to a level shifter circuit configured to generate a voltage output, including: a first charging path circuit; a second charging path circuit; and an enable circuit configured to enable the first charging path circuit and the second charging path circuit, wherein

Fast response level shifter for clamp gate control

A circuit is disclosed. The circuit includes an input port, an output port, a squelch detector and a disconnect detector. The squelch detector and the disconnect detector are enabled or disabled by a signal such that only one of the squelch detector and the disconnect detector is active at a given time. When the squelch detector is active, a threshold generator generates a squelch threshold for the squelch detector based on a squelch configuration data indicative of a predefined squelch threshold. When the disconnect detector is active, the threshold generator generates a disconnect threshold for the disconnect detector based on a disconnect configuration data indicative of a predefined disconnect threshold.
