a DECT RF Transceiver AD6411 FEATURES FUNCTIONAL BLOCK DIAGRAM Fully Compliant with DECT SpecificationsSingle IC DECT RadioIntegrated UHF VCO (External Resonator)Integrated Synthesizer Supporting Extended Frequency Allocation PLL RX Built-In Supply Regulation DEMODULATOR DATA LNA Direct VCO Modulation for DECT Transmit Path RSSI PLL-Based Demodulator PLL PFD Use with Low Cost Plastic Packaged SAW Filters TXDATA Ultralow Power Design VCO Operates from +3.0 V to +5.5 V Battery PA CONTROL User-Selectable Power-Down Modes AD6411 INTERFACE Small 48-Lead LQFP Package APPLICATIONSDECT Cordless TelephonesDECT-Based Wireless Local Loop SystemsDECT-Based Wireless Data Systems DESCRIPTION The transmit path accepts baseband data, which is filtered and The AD6411 provides the complete transmit and receive RF applied to the VCO directly. The VCO operates at half the RF signal processing necessary to implement a digital wireless carrier frequency, and is doubled to avoid pulling due to leakage transceiver based on the Digital Enhanced Cordless Telecom- from the output. munications (DECT) standard.

The limiteramplifier provides sufficient gain to drive the PLL demodulator,which provides selectable analog or sliced outputs. The RSSIoutput provides a voltage proportional to the receive signalstrength. It measures nearly 100 dB IF signal strength rangewith 14 mV/dB gain scaling.
