Mmds Tcm/qam Demodulator Fec Adc -

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. Device functionality also includes 3-wire bus Interface for configuring up to 2 Tuner synthesizers, a sigma delta Tuner IF-AGC output, a user programmable RF- AFC sigma delta output, spectrum inversion of the received signal for Tuner compatibility, and a highly configurable MPEG2-TS Interface An I 2C bus Interface provides on-board configuration and status monitoring of various functions including access to the equalizer tap values and constellation points. JTAG provides boundary scan test compatibility. By Sony Electronics
