MOTOROLA SEMICONDUCTOR TECHNICAL DATA Current information @www.mot.com.sps/ADC MC92307 Advance Information 2K - Samples FFT-Processor RESB CLK SYMSYNC The MC92307 is a pipelined Fast Fourier Transformation (FFT) processor with a blocklength of 2048 complex samples. It is especially designed for use in digital terrestrial Set-Top boxes according to the DVB-T standard for 2K transmission. One block of 2048 complex samples can be processed in 224 µs Feature Summary • • • • • • • • • • Processing of one block of 2048 complex samples (i.e. one 2K-OFDM symbol) in 224 µs. Designed for direct interfacing with Motorola’s OFDM demodulator MC92308. Input wordlength 8 bit, output accuracy selectable between 10 and 12 bit.
