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
Buffer output for weather band ag
In weather band mode the output is HIGH.
7.6
Test mode
The test mode of the IC is activated by connecting
pin FREF through a 100 k
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.

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
, C = 200 pF).
3. Human body model (R = 1.5 k
, C = 100 pF).
