STEL-1109 is a communications module that includes data path, control unit, clock generator, NCO and other modules.
The STEL-1109 is a highly integrated, maximally flexible burst transmitter targeted to the cable modem market. It receives serial data, performs randomization, Forward Error Correction (FEC), and differential encoding, maps the data to a constellation, and outputs an analog RF signal. The device is capable of operating at data rates up to 10 Mbps in BPSK mode, 20 Mbps in QPSK mode, and 40 Mbps in 16QAM mode.
