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 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. APPLICATIONS Car radios. GENERAL DESCRIPTION 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.

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...
