International Classification:

H03M 1/06

Abstract:

A serial data receiver circuit included in a computer system may include a front-end circuit, a sample circuit that includes multiple analog-to-digital converter circuits, and a recovery circuit. The front-end circuit may generate an equalized signal using multiple signals that encode a serial data stream of multiple data symbols. Based on a baud rate of the serial data stream, a determined number of the multiple analog-to-digital converter circuits sample, using a recovered clock signal, the equalized signal at the respective times to generate corresponding samples. The recovery circuit generates, using the samples, the recovered clock signal and recovered data symbols.

Abstract:

A cross-domain power control circuit is disclosed. The circuit includes a first circuit branch having a first transistor coupled to a first supply voltage node and a second circuit branch having a second transistor coupled to the first supply voltage node. A third circuit branch is coupled between a second supply voltage node and a third supply voltage node. A second supply voltage conveyed on the second supply voltage node is less than a first supply voltage conveyed on the first supply voltage node. A fourth circuit branch is coupled between the first and third supply voltage nodes. In a first mode of operation, control circuitry causes the second supply voltage to be conveyed to the third supply voltage node. In a second mode of operation, the control circuitry causes the first supply voltage to be conveyed to the third supply voltage node.
