A method of recovering a clock signal from a digital signal in a receiver includes generating a representation of an eye diagram from symbols of the digital signal, in which the symbols are sampled at a sample rate such that the representation of the eye diagram is generated by a plurality of samples. The generated representation is converted into an array of data elements having a first set of data corresponding to the plurality of samples, and a second set of data representing a plurality of data bins. A plurality of measurements are performed on the array of data elements and/or the eye diagram to obtain a plurality of measurement outputs corresponding to the plurality of samples, which are combined at each sample. A sample is selected as a clock sample based on results of the combination.

Clock recovery apparatus and method thereof

A temperature activated switching circuit, comprising a temperature activated switch Ufor switching an outputat a threshold temperature, the temperature activated switch Uhaving at least one power input VCC for receiving power; and power switching circuitry for connecting a power source to said power input VCC of the temperature activated switch U, the power source being initially disconnected from the power input VCC, and the power switching circuitry being configured to connect said power source to the power input VCC based on a detected temperature, in order to power up the temperature activated switch Ubefore said detected temperature reaches said threshold temperature.
