Vorenkamp Broadcom, Irvine, CA The increased competition to deliver broadband data to the home (including GPON and VDSL) is motivating cable providers to deliver data rates which far exceed what is presently available based on the DOCSIS 1.x and DOCSIS 2.0 standards. The DOCSIS 3.0 standard provides this bandwidth increase as well as additional flexibility, where higher data throughput can be obtained by bonding together multiple downstream (DS) channels. This standard calls for the ability to bond any 4 channels in a 64MHz contiguous RF bandwidth. Solutions that allow even more channel bonding and provide more flexibility in the allocated frequency spectrum are preferred. This paper reports an embedded dual-tuner architecture able to select two independent 32MHz frequency bands, allowing for a maximum of 10 demodulated 6MHz
