TEA6846H/V2,557 FEATURES


• FM mixer for conversion of FM RF from 65 to 108 MHzto IF of 10.7 MHz; the mixer provides inherent imagerejection
• FM RF mixer can be set to receive weather band radioup to 162.55 MHz; weather band radio flag output
• AM mixer 1 for conversion of AM RF to AM IF1 of10.7 MHz
• LC tuner oscillator providing mixer frequencies forFM mixer and AM mixer 1
• AM mixer 2 for conversion of AM IF1 to AM IF2 of450 kHz
• Crystal oscillator providing mixer frequencies forAM mixer 2 and reference for synthesizer PLL, IF count,timing for Radio Data System (RDS) update andreference frequency for car audio signal processor ICs
• Fast synthesizer PLL tuning system with local control forinaudible RDS updating
• Timing function for RDS update algorithm and controlsignal output for car audio signal processor ICs(TEA688x, SAA77xx or TEF689x)
• Digital auto alignment circuit for conversion ofLC oscillator tuning voltage to controlled alignmentvoltage of FM antenna tank circuit
• AGC PIN diode drive circuit for FM RF AGC; AGCdetection at FM mixer input; the AGC PIN diode drivecan be activated by the I2C-bus as a local or distancefunction; AGC threshold is a programmable and keyedfunction switchable via the I2C-bus
• FM IF linear amplifiers with high dynamic input range
• FM quadrature demodulator with automatic centrefrequency adjustment and Total Harmonic Distortion(THD) compensation
• Level detector for AM and FM with temperaturecompensated output voltage; starting point and slope oflevel output is programmable via the I2C-bus
• AM RF PIN diode drive circuit; AGC threshold detectionat AM mixer 1 and IF2 AGC input; threshold isprogrammable via the I2C-bus; AM IF2 AGC anddemodulator
• AM AF output switchable to provide AM IF2 forAM stereo decoder
• AM noise blanker with blanking at AM IF2
• Several test modes available for fast IC and systemtests.2

TEA6846H/V2,557 GENERAL DESCRIPTION

The TEA6846H is a single IC with car radio tuner forAM and FM intended for microcontroller tuning with theI2C-bus. It provides the following functions:
• AM double conversion receiver for LW, MW and SW(31 m, 41 m and 49 m bands) with IF1 = 10.7 MHz andIF2 = 450 kHz
• FM single conversion receiver with integrated imagerejection for IF = 10.7 MHz capable of selecting US FM,US weather, Europe FM, East Europe FM and JapanFM bands.3
