Newport Beach, California based Rockwell Semiconductor Systems Inc has announced a two device chipset that it says provides a fully integrated 1 to 30 mega samples per second Direct Broadcast Satellite receiver system. By integrating the tuner function onto a chip and re-ducting external discrete components, Rockwell said it can enable the tuner to be implemented directly onto the motherboard and reduce the cost of the receiver by up to 30%. The satellite receiver chipset is intended for use in Digital Video Broadcast and Digital Satellite System compliant consumer and commercial set-top and PC receivers and satellite ready digital VCRs. It will also enable the development of new applications such as digital satellite equipped televisions. The DBS receiver system consists of the HM1811 direct down conversion tuner chip and the HM1211 baseband DBS link chip. The HM1211 combines a DVB/DSS compliant Binary or Quadrature Phase Shift Key demodulator, Forward Error Correction and dual six bit analog to digital converters onto a single chip. The two device chipset is priced at $18 in 10,000 piece quantities. Samples are available now with production due in the second quarter. In December, Rockwell put its weight behind the proposed DOCSIS Data Over Cable System Interface Specification standard (CI No 3,301). DOCSIS is the cable industry’s attempt to keep ahead of telecommunications vendors in the delivery of high speed internet access, multimedia, videoconferencing and internet telephony.
