    摘要: Power over Ethernet (PoE) communication systems provide power and data communications over the same communications link, where a power source device (PSE) provides DC power (for example, 48 volts DC) to a powered device (PD). The DC power is transmitted simultaneously over the same communications medium with the high speed data from one node to the other node. The PSE typically includes a controller that controls the DC power provided to the PD at the second node of the communications link. The PSE controller measures the voltage, current, and temperature of the outgoing and incoming DC supply lines to characterize the power requirements of the PD. The PSE controller includes a resistorless switch to measure the current. The resistorless switch includes a sense transistor and a current mirror to allowing the PSE controller to calculate the current based upon a replica current.

    摘要: A high speed data link includes transmitter equalization and (passive) receiver equalization to compensate for frequency distortion of the data link. In one embodiment, the transmitter equalization is performed with a de-emphasis circuit. The transmitter de-emphasis circuit pre-distorts an input signal to compensate for at least some of the frequency distortion in the data caused by the transmission line. The (passive) receive equalization circuit further compensates for the frequency distortion at the output of the transmission line to flatten the amplitude response of the output signal, and thereby reduce inter-symbol interference, improve media reach and improve the bit error rate (BER).

    摘要: An ADSL transceiver chip is provided that includes an analog front-end and a digital signal processor (DSP) integrated on the same substrate. A line driver for the ADSL transceiver can be located on a separate substrate. In embodiments of the invention, the transceiver chip is implemented in a CMOS process. For example, the process could be a low voltage CMOS process. It is highly advantageous to build the analog front-end and the DSP on a single integrated IC because it allows for reduced manufacturing part count, reduced assembly time and cost. Furthermore, the line driver substrate can require a high voltage semiconductor process (e.g. 18 volts peak-to-peak) in some applications, because of the need for adequate voltage to drive the ADSL line. Whereas, the analog front-end and the DSP do not need the such a high-voltage process as required for the by the line driver 102. For example, the analog front-end and DSP can operate with 3.3 v or 5.0 v peak-to-peak. Therefore, the economies can be achieved by integrating the analog front-end and the DSP on the same substrate.
