FEATURES 2 and 8 kbytes Coded Orthogonal Frequency Division Multiplexer (COFDM) demodulator (fully DVB-T compliant: ETSI 300-744) All modes supported, including hierarchical modes Fully automatic transmission parameters detection (including Fast Fourier Transformer (FFT) size and guard interval) Digital Signal Processor (DSP) based synchronization (software can be upgraded on the fly) No extra-host software required On-chip 10-bit Analog-to-Digital Converter (ADC) 2nd or 1st IF variable analog input Only fundamental crystal oscillator required (4 MHz typical ±100 ppm) 6, 7 and 8 MHz channels with the same crystal Pulse killer algorithm to protect against impulse noise Digital frequency correction (±90 kHz) Frequency offset (±1/6 MHz) automatic estimator to speed-up the scan RF tuner input power measurement Parallel or serial transport stream interface BER measurement (before and after Viterbi decoder) Signal-to noise ratio estimation Constellation, CSI and channel frequency response outputs TPS bits I2C-bus readable (including spare ones) Controllable dedicated I2C-bus for the tuner (5 V tolerant) 3 low frequency spare DACs and 2 spare inputs CMOS 0.2 m technology. APPLICATIONS DVB-T fully compatible Digital data transmis……
