TEA6810V; TEA6811V
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.
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 I2C-bus is inoperative in the locked-tuned condition.
The reference frequency for the synthesizer and the I2C-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).
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.
