Front-end And Pll Synthesizers For Car Radios - Nxp Semiconductors

The TEA6810V and TEA6811V together with TEA6821V forms an AM/FM receiving concept for electronically tuned car Radios The TEA681xV is an FM/AM front-end with one local synthesized Oscillator for both AM and FM which is used together with the TEA6821T in a double-conversion concept. It delivers a first FM-IF of 72.2 MHz and, for MW/LW, a first AM-IF of 10.7 MHz. Minimum alignments are required due to wideband RF inputs and the common AM/FM VCO High dynamic behaviour and minimum distortion is obtained by a special RF input design combined with AGC. High sensitivity is possible in combination with RF input FETs Minimum interference is experienced due a to special synthesizer loop design and ensuring that the I 2C-bus is inoperative in the locked-tuned condition. The reference frequency for the synthesizer and the I 2C-bus information is delivered by the TEA6821V. The programmable local/dx Switch enables switching the gain of the FM mixer from normal AGC control (FM dx) to the forced 4th level of AGC (FM local). By NXP Semiconductors
