| LMX5252: Bluetooth(R) radio National Semiconductor. Powering the wireless world. LMX5242 block diagram Receiver LNA RX_DATA Control logic and serial interface Bluetooth RSSI ADC DET EQ AFC Bluetooth wireless solutions BlueRF Synthesizer SD ANT PHD 8/9 CHP 1/2 VAC Autotuner POR XO XO_N XO_P TUNE PLL_OUT Transmitter DAC PA DAC IQROM TX_DATA Introducing the next generation in Bluetooth(R) solutions National's LMX5252 Bluetooth radio provides the features and functionality designed to get you to market faster, offering a more cost effective solution than ever before. This highly integrated solution offers a 0.18 m 2.4 GHz radio. Available in a single tiny LLP-60 package (6 mm x 6 mm x 0.8 mm), the LMX5252 provides one of the smallest solutions available in the industry. I I I I I I I I I I Radio Featuring an integrated antenna filter and switch, National's radio minimizes the total number of external components. The radio additionally integrates the receiver and transmitter baluns, the antenna switch, and filter together with the VCO onto a tiny single die. The fractional-N delta-sigma synthesizer and the crystal offer support for a wide range of external reference frequency clocks and crystals. Secondary 32.768 kHz oscillator for low-power modes Typically - 84 dBm receiver sensitivity Class 2 operation Fractional-N sigma-delta modulator Operating voltage range 2.5V to 3.0V I/O voltage range 1.6V to 3.6V Several power management functions Accepts external clock 10 MHz to 40 MHz or crystal input 10 MHz to 20 MHz Current consumption typically below 41 mA Available in a LLP-36 (6 mm x 6 mm x 0.8 mm) package Blue RF interface Single Rx/Tx-pin radio interface applications Mobile handsets Personal digital assistants Personal computers Everyone wants to be connected.
