It features an exceptionally stable RSSI (Received Signal Strength Indicator) output using a unique system of detection. Supply current is less than 2mA from a supply voltage in the range 2.5V to 7.5V. FEATURES Low Power Consumption (1.5mA) Single Chip Solution Guaranteed 100MHz Operation Exceptionally Stable RSSI APPLICATIONS Cellular Radio Telephones Cordless Telephones MP18 Fig. 1 Pin connections (top view) QUICK REFERENCE DATA Supply Voltage 2.5V to 7 5V Sensitivity 3µV Co-Channel Rejection 7dB VCC 33p 270p 33k 1n 33k 8p2 17 OSCILLATOR INPUT 200mV RMS C 16 B 15 50µA E 4 OSCILLATOR TRANSISTOR 0V 40k 270p AUDIO OUTPUTS 8p2 6 20 - 40p X1 10µ 0V 220n 10p 5 2 DETECTOR 3 1µA VCC 39k 330p VCC +15dB (ADJUSTABLE) 100MHz MAX 18 8µA RFC 2k 1 8µA MIXER INPUT 3µV 1n 7 1k BIAS 8 10k 10n +1.2V 100n MIXER SL6652 +90dB (LIGHTING) 1.5MHz MAX IF AMP 11 RSSI 1k RSSI 10n 200k 200k 100n 20k 9 1.5k LOAD RESISTOR 10 CERAMIC FILTER 14 13 220n 12 220n 1.5k (TO MATCH FILTER) Fig. 2 block diagram SL6654 ABSOLUTE MAXIMUM RATINGS Supply voltage Storage temperature Operating temperature Mixer input 8V -55°C to +150°C -55°C to +125°C 1V rms ELECTRICAL CHARACTERISTICS Test conditions (unless otherwise stated): VCC = 2.5V to 7.5V, Tamb = -30°C to +85°C, IF = 455kHz, RF = 50MHz, Quad Coil Working Q = 30 Value Characteristics Min.
