M64886FP RF Transceiver for Short-range Wireless REJ03F0087-0100Z Rev.1.0 Sep.22.2003 Description The M64886FP is a semiconductor integrated circuit designed for RF / IF / AF transceiver function with Dual PLL synthesizer for double conversion system cordless phone which used by 2.4 GHz and 900MHz ISM band of North America. It contains dual PLL and VCO circuit for RX / TX, PA for transmission output, double balance type mixer for the 1st and 2nd intermediate frequency, LIM and RSSI and Demodulator for 5.5 MHz, Expander (include volume www.DataSheet4U.com control function) / Compressor (include IDC, Splutter Filter block) and Speaker / Microphone Amp for Audio signal. It is possible to control level of TX power by external variable resistor. It is designed using a high-frequency BiCMOS process and contributes to reduce size of system and power consumption. Features • Receiver It is possible to construct double conversion system. Built in 1st MIX for 1st IF which can respond up to 2.4 GHz band. Built in 2nd MIX and LIMITTER and RSSI and Demodulator for 2nd IF. Built in Expander and Speaker Amp for Audio signal. • Transmission Built in PA (Pout = –1dBm max) which can respond up to 2.4 GHz band. It is possible to control level of power by external variable resistor. Out put is differential type, it is need to connect to RF filter with a balun circuit. Built in Microphone Amp and Compressor and IDC and Splutter Filter for Audio signal. • Synthesizer Built in Differential type VCO for TX and RX which can respond up to 1.2 GHz band. Built in 2-multiple circuit which can respond up to 2.4 GHz band. Built in 2-modulus prescaler which can respond up to 1.2 GHz band. Built in current output type charge pump. Built in B-E Colpitts type crystal oscillation for reference frequency. • Current consumption Stand by mode = PLL+VCO+ DBL+LO+MIX+IF = 28 mA Typ. TX / RX mode (ID) = Stand by + PLL+VCO+DBL+PA = 55 mA Typ. TX / RX mode (Talk) = TX / RX mode (ID) +AF+SP = 65 mA Typ. Off mode = < 50 µA Rev.1.0, Sep.22.2003, page 1 of 27 M64886FP Block Diagram 1.
