A SELECTABLE-TAP EQUALIZER, AUTO-CONFIGURED EQUALIZER, RECEIVING CIRCUIT HAVING AN EQUALIZER CALIBRATION FUNCTION, AND SYSTEM HAVING GROUPED REFLECTION CHARACTERISTICS

摘要

A selectable-tap equalizer, auto-configured equalizer, receiving circuit having an equalizer calibration function, and system having grouped reflection characteristics is provided. The selectable-tap equalizer includes a buffer, a select circuit and an equalizing circuit. The auto-configured equalizer includes a scoping circuit, buffer circuit, select circuit and equalizing circuit. The receiving circuit includes a sampling circuit, output driver and clock signal generator. The system includes a transmit circuit, a receive circuit, and a signal path coupled between the transmit circuit and the receive circuit. The signal path includes a first signal path segment coupled between the transmit circuit and a first interface, and a second signal path segment coupled between the receive circuit and a second interface, the second signal path having an electrical length that is substantially equal to an electrical length of the first signal path segment.
