Broadcom Corporation - BCM3037 - QAMlink® Upstream Burst Modulator

The BCM3037 provides a complete /4 DQPSK, QPSK and 16-QAM Upstream Burst Modulator and FEC encoder integrated on a single chip. A burst FIFO Buffer provides input data rate decoupling. The FEC encoder consists of a programmable randomizer and a programmable RS encoder. There is also a programmable preamble prepend, programmable symbol mapper, and a programmable transmitter preequalizer. The Modulator consists of dual square-root raised cosine Filters with programmable excess bandwidth, =0.25 or =0.50, interpolation Filters and a digital upconverter which translates the shaped pulse to a digitally tunable IF center frequency. An integrated 10-bit DAC then converts this signal to an Analog waveform with programmable attenuation. The BCM3037 accepts a serial data stream and transmit control inputs. The output consists of an Analog modulated and filtered data burst containing data at variable symbol rates and three modulation formats, which are /4 DQPSK, QPSK and 16-QAM. Modulation CAN include differential or non-differential encoding. The modulated burst consists of a power up, ramp up, preamble, data, FEC, ramp down, guard time and power down in each burst. The output of the BCM3037 CAN then be sent to a power Amplifier There are standard DAVIC A0 and ATM UTOPIA serial input Interfaces provided. There is also a generic byte-based Interface Alternatively, the BCM3037 CAN be configured to provide a data bit Clock for synchronizing data. Control information is input through either an I2C-compatible or SPI-compatible serial Interface
