7.3.5
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.
7.3.6
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 I
7.4
The test mode of the IC is activated by:
8
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
2. Machine model (R = 0 , C = 200 pF).
3. Human body model (R = 1.5 k , C = 100 pF).
