PRODUCTION DATA. AFE031 SBOS531E – AUGUST 2010 – REVISED JUNE 2019 AFE031 Powerline Communications Analog Front-End 1 1 Features 1 • Integrated powerline driver with thermal and overcurrent protection • Conforms to EN50065-1 • PRIME certified • Large output swing: 12 VPP at 1.5 A (15-V supply) • Low power consumption: 15 mW (receive mode) • Programmable Tx and Rx filters • Supports EN50065 CENELEC bands A, B, C, D • Supports FSK, S-FSK, and OFDM • Supports PRIME, G3, IEC 61334 • Receive sensitivity: 20 μVRMS, typical • Programmable Tx and Rx gain control • Four-wire serial peripheral interface • Two integrated zero crossing detectors • Two-wire transceiver buffer • 48-Pin QFN PowerPAD™ package • Extended junction temperature range: –40°C to +125°C 2 Applications • eMetering • Lighting • Solar • Pilot wire 3 Description The AFE031 is a low-cost, integrated, powerline communications (PLC) analog front-end (AFE) device that is capable of capacitive- or transformer-coupled connections to the powerline while under the control of a DSP or microcontroller. It is ideal for driving low- impedance lines that require up to 1.5 A into reactive loads. The integrated receiver is able to detect signals down to 20 μVRMS and is capable of a wide range of gain options to adapt to varying input signal conditions. This monolithic integrated circuit provides high reliability in demanding powerline communications applications. The AFE031 transmit power amplifier operates from a single supply in the range of 7 V to 24 V. At maximum output current, a wide output swing provides a 12-VPP (IOUT = 1.5 A) capability with a nominal 15-V supply. The analog and digital signal processing circuitry operates from a single 3.3-V power supply.
