Introduction The DRX 3975D is a fourth-generation COFDM demodulator that offers today’s highest level of frontend integration resulting in ultimate DVB-T digital reception, pliant to ETS 300 744, DTG D-Book, EICTA E-Book, and Nordig Unified v1.0.2 . The IC applies cutting-edge digital filtering techniques in bination with a high-performance A/D-converter and PLL configuration, resulting in superior performance figures in the presence of digital- and analog adjacent channels. Progressive channel estimator algorithms provide exceptional performance in multipath- and dynamicecho conditions - an especially important feature for single-frequency networks and indoor reception. The state-of-the-art impulsive noise cruncher suppresses interferences originating from sources such as cars, electrical motors, and household appliances. 1.1. Features - Highest level of front-end integration and flexibility: - Single 8 MHz SAW filter operation - 2 AGC control signals available for RF and IF amplifier control - Flexible clock reference options - Re-use of 4 MHz tuner clock reference - Pre-SAW sense input for optimal...
