Check for Samples: AFE030 FEATURES DESCRIPTION Integrated Powerline Driver with Thermal and
Overcurrent Protection Conforms to EN50065-1 Pin-Compatible to AFE031 Large Output Swing: 13 VPP at 1.0 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 OFDM, FSK, and S-FSK Supports IEC 61334 Receive Sensitivity: 20 ОјVRMS, Typical Programmable Tx/Rx Gain Control Four-Wire Serial Peripheral Interface Two Integrated Zero Crossing Detectors Two-Wire Transceiver Buffer Package: QFN-48 PowerPADв„ў Extended Junction Temperature Range:
–40°C to +125°C The AFE030 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 digital signal processor (DSP) or microcontroller.
It is ideal for driving low-impedance lines that require
up to 1.0 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 The AFE030 is internally protected against
overtemperature and short-circuit conditions. It also
provides an adjustable current limit. An interrupt
output is provided that indicates both current limit and
thermal limit. There is also a shutdown pin that can
be used to quickly put the device into its lowest …
