Abstract: A high-speed bit stream interface module interfaces a high-speed communication media to a communication Application Specific Integrated Circuit (ASIC) via a Printed Circuit Board (PCB). The high-speed bit stream interface module includes a line side interface, a board side interface, and a signal conditioning circuit. The line side interface includes a media coupler that receives the line side media, either copper media or optical media. The board side interface couples the high-speed serial bit stream interface module to the PCB. A signal conditioning circuit communicatively couples to the line side interface and to the board side interface. The signal conditioning circuit receives an RX signal from the line side interface, conditions the RX signal, and provides the RX signal to the board side interface. The signal conditioning circuit receives a TX signal from the board side interface, conditions the TX signal, and provides the TX signal to the board side interface.

Abstract: Aspects of the invention may provide a method and system for adjusting a gain and/or a frequency response of an input signal for a multimode PHY device. A signal divider (704) may apportion the input signal into a gain adjustment signal and/or an equalization adjustment signal upon receipt of the input signal. A signal adjuster (702) coupled to the signal divider (704) may adjust a gain of the apportioned gain adjustment signal within the multimode PHY device (130). An equalizer (706) coupled to the signal divider (704) may be configured to equalize the equalization adjustment signal within the multimode PHY device (130). A summer (708) coupled to the equalizer (706) and signal adjuster (702) may be adapted to sum the adjusted adjustment signal and the equalized equalization adjustment signal within the multimode PHY device (130) to create an output equalized signal (712) having a desired gain and/or frequency response.

Abstract: A circuit and method is disclosed for self trimming in frequency acquisition and clock recovery. The circuit can be simplified as having a VCO in communication with three loops including a trimming loop, a frequency loop and a phase loop. The trimming loop includes a ramp generator for supplying a steady increase of bias current to the VCO causing the frequency of the VCO to increase. At each step, the averaged output of the frequency detector is measured by a comparator. A decision circuit included in the trimming loop registers the output of the comparator in digital format. The trimming loop continues until the decision circuit detects a long string of positives followed by a long string of negatives and at this point, the trimming loop is shut off and the frequency loop is in operation. The frequency loop drives the VCO frequency to within a small difference of the incoming data frequency. The phase loop cleans up the data and locks the phase.
