Ich hab' noch was gefunden:
Features:
-DC switchable scaling factor /960 /1024
-U665B without self oscillation
-U865BS with self oscillation
-large operation frequency range
-few external components
-output signal and switching voltage at U865BS are inverted in opposite to U665B
Supply voltage range: Pin8 Vs= 4,5V .. 5,5V Supply current Vs=5V: Pin8 Is= 52mA .. 78mA Large signal compatibility, Rg= 50 Ohm: Pin2 Vimax >= 300mV Input sensivity f=80MHz..1GHz, Rg = 50 Ohm: Pin2 Vi = 20mV Switching voltage: Pin6 Vh > 2,3V Vl < 0,8V
Und dann noch ein Blockdiagramm des Bausteins:
