The BCM3138 QAMLink? Universal QPSK/QAM burst receiver is a highly integrated solution that significantly decreases the board space and cost of demodulators in digital cable modem head-ends applications. The BCM3138 provides two independent cable network receivers that accept QPSK and m-QAM burst data in frequency-agile, time-division multiple access (TDMA) schemes. Advanced features in the BCM3138 include an analog front end (AFE), a QAM demodulator, a generalized equalizer and an enhanced Reed Solomon (RS) FEC decoder with dynamic deinterleaving.
