Description
The CXD1958Q is an integrated TCM/QAM demodulator for MMDS systems using the DAVIC MMDS standard. This highly integrated device incorporates an internal 8-bit ADC, image rejection and root-raised cosine filters, all-digital symbol timing recovery PLL, adaptive decision feedback equalizer (DFE) with 10 feedforward and 30 feedback taps, 4-D TCM decoder, and DAVIC/DVB compliant forward error correction comprising (204,188) Reed Solomon decoder, a programmable de-interleaver with I = 12 and I = 204, and a de-randomiser. All internal clocks are generated from a single external 30MHz reference crystal.
Features
? DAVIC MMDS V1.1 and V1.3 compliant
? Supports 16, 64 and 256QAM
? Supports 16, 64 and 256 TCM
? Internal 8-bit ADC
? Interface for 10-bit external ADC
? 36.125MHz nominal IF input
? Symbol rate range 5 – 5.304Mbaud in 6MHz channels
? Integrated matched filtering with 0.15 roll-off factor
? ±400KHz internal carrier offset compensation with negligible losses @ 5Mbaud 6MHz channel
