Low frequency communication signal state detection |
| abstract |
Various techniques are provided to detect a state of a communication signal. In one example, a method of detecting a state of a signal includes receiving a differential communication signal comprising a positive portion and a complementary negative portion. The method also includes filtering the positive portion of the communication signal through a first low pass filter to provide a filtered positive portion of the communication signal. The method also includes filtering the negative portion of the communication signal through a second low pass filter to provide a filtered negative portion of the communication signal. The method also includes comparing the filtered positive portion of the communication signal with an internal reference voltage. The method also includes comparing the filtered negative portion of the communication signal with the internal reference voltage. The method also includes generating a low frequency detect signal in response to the comparing operations to indicate whether the communication signal is in a low frequency state. |
