Manufacturer:DS Description:TheDS1621ZprovidescompleteStarvueII, DOCSIS/EuroDOCSISandDVB/DAVICcompatible 4/16-QAM upstream burst FEC encoder and modulator functionality. A 1-KB burst FIFO buffer provides input data rate decoupling. The FEC encoder consists of a programmable randomizer and Reed-Solomon encoder. There is also a programmable preamble prepend, symbol mapper, and transmitter pre-equalizer. 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 RF center frequency from 0C65 MHz. A 10-bit D/A then converts this signal to an analog waveform with programmable output power levels. |
