INTEGRATED CIRCUITS DATA SHEET TEA6810V; TEA6811V Front-end and PLL synthesizers for car radios Product specification Supersedes data of September 1994 File under Integrated Circuits, IC01 1996 Jun 18 Philips Semiconductors Product specification Front-end and PLL synthesizers for car radios TEA6810V; TEA6811V FEATURES * Synthesizer function which includes a Voltage Controlled Oscillator (VCO), dividers, phase detector, charge-pump and in-lock detector * FM mixer with AGC * AM RF amplifier with AGC * AM mixer. Minimum alignments are required due to wideband RF inputs and the common AM/FM VCO. APPLICATIONS 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. * Car radios. GENERAL DESCRIPTION Minimum interference is experienced due a to special synthesizer loop design and ensuring that the I2C-bus is inoperative in the locked-tuned condition. The TEA6810V and TEA6811V, together with TEA6821V forms an AM/FM receiving concept for electronically tuned car radios. The reference frequency for the synthesizer and the I2C-bus information is delivered by the TEA6821V. 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. 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).
