TEA6845H
TEA6845H - Brand New PHILIPS RF Receivers
- One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
GENERAL DESCRIPTION
The TEA6845H is a single IC with car radio tuner for AM and FM intended for microcontroller tuning with the I2C-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 and IF2 = 450 kHz**
• FM single conversion receiver with integrated image rejection for IF = 10.7 MHz capable of selecting US FM, US weather, Europe FM, East Europe FM and Japan FM bands.
FEATURES
• FM mixer for conversion of FM RF from 65 to 108 MHz to IF of 10.7 MHz; the
mixer provides inherent image rejection
• FM RF mixer can be set to receive weather band radio up to 162.55 MHz;
weather band radio flag output
• AM mixer 1 for conversion of AM RF to AM IF1 of 10.7 MHz
• LC tuner oscillator providing mixer frequencies for FM mixer and AM mixer 1
• AM mixer 2 for conversion of AM IF1 to AM IF2 of 450 kHz
• Crystal oscillator providing mixer frequencies for AM mixer 2 and reference
for synthesizer PLL, IF count, timing for Radio Data System (RDS) update and
reference frequency for car audio signal processor ICs
• Fast synthesizer PLL tuning system with local control for inaudible RDS
updating
• Timing function for RDS update algorithm and control signal output for car
audio signal processor ICs (TEA688x, SAA77xx or TEF689x)
• Digital auto alignment circuit for conversion of LC oscillator tuning
voltage to controlled alignment voltage of FM antenna tank circuit
• AGC PIN diode drive circuit for FM RF AGC; AGC detection at FM mixer input;
the AGC PIN diode drive can be activated by the I2C-bus as a local or distance
function; AGC threshold is a programmable and keyed function switchable via
the I2C-bus
• FM IF linear amplifiers with high dynamic input range
• FM quadrature demodulator with automatic centre frequency adjustment and
Total Harmonic Distortion (THD) compensation
• Level detector for AM and FM with temperature compensated output voltage;
starting point and slope of level output is programmable via the I2C-bus
• AM RF PIN diode drive circuit; AGC threshold detection at AM mixer 1 and IF2
AGC input; threshold is programmable via the I2C-bus; AM IF2 AGC and
demodulator
• AM AF output switchable to provide AM IF2 for AM stereo decoder
• AM noise blanker with blanking at AM IF2
• Several test modes available for fast IC and system tests.
