Product Summary

The BCM3440KQTE is an advanced modulation satellite receiver. It brings a new level of performance to the satellite television industry with the introduction of an integrated advanced modulation receiver and turbo FEC decoder. The BCM3440KQTE contains dual 7-bit A/D converters, an all-digital variable rate BPSK/QPSK/8PSK/16QAM receiver, an advanced modulation turbo FEC decoder, and a DVB/DIRECTV/DCII compliant FEC decoder. The BCM3440KQTE also features a simplified user interface employing an on-chip microcontroller for all system configuration, acquisition, control, and monitoring functions.
