Assignee:

Marvell International Ltd.

International Classification:

H03D 13/00

US Classification:

327 12, 327156

Abstract:

In one embodiment, a phase detector is provided comprising a first input, a second input, and first circuitry in communication with the first and second inputs, the first circuitry operative to provide an indication of a phase difference between a first signal supplied by the first input and a second signal supplied by the second input, wherein an aberration in one of the first and second signals results in an incorrect indication of phase difference. The phase detector also comprises second circuitry in communication with the first circuitry, the second circuitry operative to provide a correct indication of phase difference despite the aberration in the at least one of the first and second signals. In another embodiment, a differential phase detector is provided.

Filed:

Jun 16, 2008

Appl. No.:

12/139979

Inventors:

Yingxuan Li - Saratoga CA, US
Qing Yang - San Jose CA, US

Assignee:

Marvell International Ltd.

International Classification:

H04B 1/16

US Classification:

455340, 455339, 4552261, 455227

Abstract:

The following embodiments relate to an analog filter having an adjustable transfer function for use in a system or circuit that processes a signal having a changing data rate. The transfer function may be adjusted by adjusting the resistance and/or capacitance of components of the analog filter. The analog filter is calibrated based on an optimum operational parameter at a certain data rate, such as a median data rate. The analog filter may be further adjusted as the data rate of the signal changes.
