Appl. No.:

13/247295

Inventors:

Love KOTHARI - Sunnyvale CA, US
Ajat HUKKOO - Cupertino CA, US
Kerry Alan THOMPSON - Fort collins CO, US

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H04W 88/02

US Classification:

455572

Abstract:

A communications device is disclosed that implements a phase-locked-loop to multiply a clock signal provided to a power management unit (PMU) by a variable integer value. Multiplying the PMU clock signal provides a second clock signal where the second clock signal is characterized by a fundamental component with one or more harmonics of the fundamental component that differ from the fundamental component and the one or more harmonics of the PMU clock signal. The fundamental component with one or more harmonics of the second clock signal does not occupy the same communication channel as the transmission communication signal of the communications device. Thus, minimizing the degradation of the transmission communication signal.

Abstract:

An integrated circuit is disclosed that contains both a PMU and another processing portion, such as a baseband. Because of the limited pins devoted to the PMU, the PMU receives most of its signals through the other processing portion of the integrated circuit, Thus, in order to protect the PMU, the integrated circuit isolates the PMU portion from receiving different signals from the other processing portion until after certain conditions are satisfied. In addition, the integrated circuit includes a GPIO pin bank in the other processing portion that can be freely configured so as to allow for testing of the PMU.
