UNIVERSAL ADVANCED DOWNSTREAM 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.
