Product Summary

The Q1900C-1N is a VITERBI/TRELLIS decoder. The Q1900C-1N forward error correction improves the bit error rate performance of power limited and bandwidth limited channels by adding structured redundancy to the transmitted data. The type of additive noise experienced on the channel determines the class of FEC used on the channel. Tree codes of the Q1900C-1N are used for channels with additive white gaussian noise and block codes are used for channels with additive burst noise.

Parametrics

Q1900C-1N absolute maximum ratings: (1)Storage temperature: -65 to +150℃; (2)Junction temperature: +150℃; (3)Voltage on any input pin: -0.3 VDD+0.3V; (4)Voltage on VDD and on any output pin: -0.3 to +7V.

Features

Q1900C-1N features: (1)Viterbi mode rates 1/3, 1/2, 3/4 and 7/8; (2)Threllis mode rates 2/3 and 3/4; (3)Full duplex encode and decode in both viterbi and Trellis modes; (4)Large coding gains at Eb/No of 10 5; (5)3 bit soft decision or 1 bit hard decison decoder inputs for viterbi mode; (6)Easy implementation of additional code rates.
