A highly integrated set-top box is implemented on a single semiconductor substrate. For instance, an analog RF tuner is implemented on the same substrate with a digital receiver, and audio-video back-end circuits. The single chip set-top box can be used for satellite, cable, internet, or terrestrial TV applications, or other applications. As a result, the substrate area, assembly time, and associated costs per chip are reduced.

Aspects of a method and system for blocking data in scan registers from being shifted out of a device may comprise preventing data intrusion in an integrated circuit by generating a device reset signal prior to entering scan mode. The method may further comprise detecting an attempt to enter said scan mode. The device reset signal may also be an internal reset signal. A subsequent device reset signal may be generated after entering scan mode. The subsequent device reset signal may be an internal pulse signal. The method may further comprise clearing stored data in an integrated circuit after generating a subsequent device reset signal.

A communication unit () arranged to send transmit data includes a receiver () arranged to recover input data transmitted at a downstream transfer rate in response to a symbol clock () signal. A transmitter () is arranged to transmit the transmit data at an upstream transfer rate in response to an upstream transmit clock signal (TX_CLKA) that is coordinated with the symbol clock signal. The frequency or repetition rate of the upstream transmit clock signal is defined at least in part by a predetermined relationship between the downstream transfer rate and the upstream transfer rate, such as a ratio of the downstream transfer rate and the upstream transfer rate.
