A transceiver includes a receiver section and a transmitter section. The receiver section includes a clocking circuit, a serial-to-parallel module, and compensation. The transmitter section includes a clocking circuit, parallel-to-serial module, and compensation. The compensation within the receiver section and transmitter section compensates for integrated circuit (IC) processing limits and/or integrated circuit (IC) fabrication limits within the clocking circuits, serial-to-parallel module, and parallel-to-serial module that would otherwise limit the speed at which the transceiver could transport data.

An integrated circuit may be initialized by determining that the supply voltage is ramping up and resetting logic in the integrated circuit to a predetermined initial state using a reset signal. After the logic is determined to be in its initial state and the supply voltage is established, the reset signal may be latched off.

A system for calibrating an adjustable termination resistor for a low voltage differential signaling (LVDS) system is provided. The system includes an adjustable termination resistor located on a chip and a reference termination resistor located off the chip. A bias circuit coupled to the adjustable termination resistor and the reference termination resistor causes the same current to flow through the adjustable termination resistor and the reference termination resistor. A comparator is configured to compare a first voltage drop across the adjustable termination resistor and a second voltage drop across the reference termination resistor. A control circuit is coupled to receive an output signal from the comparator. If the output signal indicates that the adjustable termination resistor has a desirable value with respect to the reference termination resistor, then the control circuit stops the calibration operation. Otherwise, the control circuit modifies the adjustable termination resistor and repeats the calibration cycle.
