10 / 66 page  2003 Dec 19 10 Philips Semiconductors Product specification New In Car Entertainment (NICE) extended car radio TEA6842H 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. Trigger sensitivity can be modified by 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. 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 k Ω resistor to VDDA1. 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. 8 LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 60134). 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. 2. Machine model (R = 0 Ω, C = 200 pF). 3. Human body model (R = 1.5 k Ω, C = 100 pF). SYMBOL PARAMETER CONDITIONS MIN. MAX.
