SL6654

LOWER POWER IF/AF CIRCUIT (WITH RSSI) FOR FM CELLULAR RADIO

Zarlink Semiconductor Inc 

SL6654

Supply voltage

The SL6652 will operate reliably from 2.5V to 7.5V The

supply line must be decoupled with 470nF using short leads.

Detector

The internal band gap reference must be externally

decoupled. It can be used as an external reference but must

not be loaded heavily; the output impedance is tyically 14

ohms.
