U4275B
Description
The U4275B is a bipolar integrated receiving conditions analyser as well as multipath noise cancellation circuit
Key Features
- The fieldstrength voltage at FSIN is initially buffered so as not to impair the characteristics of the IF IC and is available at BFSOUT
- 2 Preliminary Information Rev
- Blanking occurs when the voltage at the MUTE pin falls below 1 V
- A voltage in the range VS/2 > 1 V defines the switching threshold as from which multipath interference is signalled at pin INT
- In all other cases, the MPX signal passes through the IC unchanged
