It is ideal for driving low- impedance lines that require up to 1.5 A into reactive • Large Output Swing: 12 VPP at 1.5 A loads. The integrated receiver is able to detect (15-V Supply) signals down to 20 μVRMS and is capable of a wide • Low Power Consumption: range of gain options to adapt to varying input signal 15 mW (Receive Mode) conditions. This monolithic integrated circuit provides high reliability in demanding powerline • Programmable Tx and Rx Filters communications applications. • Supports EN50065 CENELEC Bands A, B, C, D The AFE031 transmit power amplifier operates from a • Supports FSK, S-FSK, and OFDM single supply in the range of 7 V to 24 V. At • Supports PRIME, G3, IEC 61334 maximum output current, a wide output swing • Receive Sensitivity: 20 μVRMS, Typical provides a 12-VPP (IOUT = 1.5 A) capability with a nominal 15-V supply. The analog and digital signal • Programmable Tx and Rx Gain Control processing circuitry operates from a single 3.3-V • Four-Wire Serial Peripheral Interface power supply. • Two Integrated Zero Crossing Detectors The AFE031 is internally protected against • Two-Wire Transceiver Buffer overtemperature and short-circuit conditions. It also • 48-Pin QFN PowerPAD™ Package provides an adjustable current limit. An interrupt output is provided that indicates both current limit and • Extended Junction Temperature Range: thermal limit. There is also a shutdown pin that can –40°C to +125°C be used to quickly put the device into its lowest power state. Through the four-wire serial peripheral APPLICATIONS interface, or SPI™, each functional block can be • eMetering enabled or disabled to optimize power dissipation. • Lighting The AFE031 is housed in a thermally-enhanced, • Solar surface-mount PowerPAD package (QFN-48). Operation is specified over the extended industrial • Pilot Wire junction temperature range of –40°C to +125°C. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 PowerPAD, C2000 are trademarks of Texas Instruments. 3 SPI is a trademark of Motorola, Inc. 4 All other trademarks are the property of their respective owners.
