Abstract
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.
Claims19
A circuit, comprising:
- an input port, an output port, a squelch detector and a disconnect detector, wherein 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, wherein 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, wherein 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, the circuit further including a RC network coupled with the input port, wherein the RC network includes a first resistor R1 and a first capacitor C1, a second resistor R2 and a second capacitor C2.
A circuit, comprising:
- an input port, an output port, a squelch detector, a disconnect detector and an switchable RC network, wherein 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, wherein when the disconnect detector is active, the switchable RC network is switched to provide a predefined ratio resistor divider between the input port and an output of the switchable RC network and when the squelch detector is active, the RC network is bypassed.
