Integrated Set-Top Box with Daisy-Chaining
First Claim
1. A set-top box, comprising:
- a common carrier;
a down-stream path having a tuner and a digital receiver portion, the tuner disposed on a first substrate attached to the common carrier, and the digital receiver portion disposed on a second substrate attached to the common carrier;
an up-stream path having a power amplifier disposed on the second substrate with the digital receiver portion; and
a daisy-chain buffer having an input coupled to an input of the tuner and having an output coupled to an input of a further receiving entity, the daisy-chain buffer configured to provide a signal to drive the further receiving entity.

Abstract
The present invention is an integrated set-top box having daisy-chaining capability. The set-top box includes a down-stream path having a tuner and a digital receiver portion and an up-stream path having a power amplifier. In one embodiment, the tuner, digital receiver, and power amplifier can all be disposed on a common substrate. In another embodiment, the tuner can be disposed on a first substrate, and the digital receiver and the power amplifier can be disposed on a second substrate. The set-top box includes a daisy-chain buffer having an input coupled to an input of the tuner and having an output coupled to an input of another receiving entity such as another set-top box, tuner, cable, etc., where the daisy-chain buffer is configured to provide a signal to drive the receiving entity.
