7 FUNCTIONAL DESCRIPTION
7.1 Oscillators
7.1.1 VCO
TheL and CtunedVCO provides the local oscillator signal
for both FM and AM mixer 1. It has a frequency range of
151.2 to 248.2 MHz.
7.1.2 CRYSTAL OSCILLATOR
The crystal oscillator provides a 20.5 MHz signal that is
used for:
• Reference frequency for frequency synthesizer PLL
• Local oscillator for AM mixer 2
• Reference frequency for the IF counter
• Timing signal for the RDS update algorithm
• Referencefrequency(75.368 kHz)fortheTEA688x(car
audio signal processor - CASP) or TEF689x (car radio
integrated signal processor - CRISP).
7.1.3 PLL
Fast synthesizer PLL tuning system with local control for
inaudible RDS updating.
7.2 FM signal channel
7.2.1 DAA
FM RF Digital Auto Alignment (DAA) circuitry for the
conversion of the VCO tuning voltage to a controlled
alignment voltage for the FM antenna tank circuit.
TEA6842H
If the keyed AGC function is activated, the AGC function is
keyed by the narrow band level (IF).
The AGC PIN diode drive can be set via the I2C-bus to
local function for search tuning.
7.2.4 FM IF AMPLIFIERS
The two FM IF amplifiers provide 10 dB and 8.5 dB
amplification with high linearity and dynamic range.
7.2.5 FM DEMODULATOR
The FM quadrature demodulator includes automatic
centre frequency adjustment and THD compensation.
7.2.6 FM MPX SOFT MUTE
Muting depth and start of muting are adjustable via the
I2C-bus.
7.2.7 ULTRASONIC NOISE DETECTOR
This is an ultrasonic noise detector with programmable
sensitivity by external resistor. The gain of the ultrasonic
noise detector also depends of the RF level.
Attack and decay time can be set with an external timing
capacitor. The detector has a buffered output.
7.3 AM signal channel
7.3.1 AM TUNER
The AM tuner is realized in a double conversion technique
and is capable of selecting LW, MW and SW bands.
7.2.2 FM I/Q MIXER
FM quadrature mixer converts FM RF (65 to 162.55 MHz)
to IF of 10.7 MHz. The FM mixer provides inherent image
rejection and high RF sensitivity.
It is capable of tuning the US FM, US weather,
Europe FM, Japan FM and East Europe FM bands:
• US FM = 87.9 to 107.9 MHz
• US weather FM = 162.4 to 162.55 MHz
• Europe FM = 87.5 to 108 MHz
• Japan FM = 76 to 91 MHz
• East Europe FM = 65.8 to 74 MHz.
7.2.3 FM KEYED AGC
The AGC threshold is programmable and the keyed AGC
function is switchable via the I2C-bus.
2003 Dec 19 9
AM mixer 1 converts AM RF to IF1 of 10.7 MHz, while
AM mixer 2 converts IF1 of 10.7 MHz to IF2 of 450 kHz:
• LW = 144 to 288 kHz
• MW = 522 to 1710 kHz (European and US AM band)
• SW = 5.85 to 9.99 MHz (including the 31 m, 41 m and
49 m bands).
7.3.2 AM RF AGC AND IF2 AGC
The AM RF includes a PIN diode drive circuit. The
threshold detection points for AM AGC are performed at
AM mixer 1 and AM IF2. AGC thresholds are
programmable at AM mixer 1 input via the I2C-bus.
7.3.3 AM AF OR IF2 SWITCH
The AM output provides either a demodulated AM Audio
Frequency (AF) or the corresponding AM IF2 signal. The
IF2 signal can be used for AM stereo decoder processing.
Philips Semiconductors Product specification
New In Car Entertainment (NICE)
extended car radio
7.3.4 AM SOFT MUTE
The AM detector output is either not muted or signal
strength dependent soft muted audio. The soft mute
function can be switched off via the I2C-bus.
7.3.5 AM NOISE BLANKER
The detection point for the AM noise blanker is the output
stage of AM mixer 1, while blanking is realized at the
output of the mixer 2.
Triggersensitivitycanbemodifiedby changing the resistor
value at pin AMNBHOLD.
7.4 FM and AM level detector
FM and AM level detectors provide the temperature
compensated output voltage. The starting points and
slopes of the level detector outputs are programmable via
the I2C-bus.
TEA6842H
7.5 Input for external mute
A LOW signal at pin MUTE starts muting with 1 ms slope.
Mute is active as long as the control voltage is LOW.
A HIGH at pin MUTE stops muting with 1 ms slope.
7.6 Buffer output for weather band flag
In weather band mode the output is HIGH.
7.7 Test mode
The test mode of the IC is activated by connecting
pin FREF through a 100 kΩ resistor to V
The test mode is intended for IC test during IC and radio
manufacturing.
In test mode the settling time of the AM IF2 AGC is
reduced to less than 100 ms in the nominal application.

Notes
1. To avoid damages and wrong operation it is necessary to keep all 8.5 V supply voltages at a higher level than any
5 V supply voltage. This is also necessary during power-on and power-down sequences. Precautions have to be
provided in such a way that interferences can not pull down the 8.5 V supply below the 5 V supply.
