Broadcom Corporation - BCM3034 - Universal 1024-QAM Modulator

The BCM3034 QAMLink Universal Modulator is a highly integrated solution that significantly decreases the board space and cost of Modulators in digital cable-TV head-ends, digital cable modem head-ends, digital Microwave Radio SMATV and MMDS applications. The BCM3034 features an advanced downstream QAM Modulator that includes an extended ITU-T J.83 Annex A/B/C FEC encoder, an all-digital QAM Modulator supporting up to 1024-QAM, and an integrated 10-bit D/A Converter with power control. Additionally, the BCM3034 includes a second Modulator that CAN be used for out-of-band signaling or CPE power control. The BCM3034 is a flexible, cost-effective worldwide solution. Because the chip accepts variable data rates and supports multiple digital transmission standards, manufacturers only need to develop one Modulator for worldwide usage. The integrated feature set in the BCM3034 significantly reduces the board space in Modulators giving manufacturers a chip solution that is both cost-effective and easy to use.
