Check for Samples: AFE031 FEATURES DESCRIPTION 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 ОјVRMS, Typical Programmable Tx and Rx Gain Control Four-Wire Serial Peripheral Interface Two Integrated Zero Crossing Detectors Two-Wire Transceiver Buffer 48-Pin QFN PowerPADв„ў Package Extended Junction Temperature Range:
–40°C to +125°C 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 lowimpedance lines that require up to 1.5 A into reactive
loads. The integrated receiver is able to detect
signals down to 20 ОјVRMS 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. 1 234 APPLICATIONS
