ST ST7570 S-FSK动力线网络解决方案

ST公司的ST7570是S-FSK动力线网络系统级芯片(SoC),包括高性能PHY处理器核和协议控制器核,以及模拟前端(AFE)和线路驱动器,50Hz时的可编程比特率高达2.4kbps,1Hz步长的可编载波高达148.5 kHz,8-18V功率放大器电源,3.3V或5V数字I/O电源,是符合IEC61334-5-1 S-FSK标准的性价比最好的单片动力线通信解决方案.本文介绍了ST7570主要特性,方框图以及电路图,材料清单和PCB布局图.

The ST7570 is a powerful power line networking system-on-chip. It combines a high-performance PHY processor core and a protocol controller core with a fully integrated analog front end (AFE) and line driver.

The ST7570 features allow the most costeffective, single-chip power line communication solution based on IEC61334-5-1 S-FSK standard. Realized using a multi-power technology with state-of-the-art VLSI CMOS lithography, the ST7570 is based on dual digital core architecture (a PHY processor engine and a protocol controller core) to guarantee outstanding communication performance with a high level of flexibility and programmability.

The on-chip analog front end, featuring analog to digital and digital to analog conversion and automatic gain control, plus the integrated power amplifier delivering up to 1Arms output current, makes the ST7570 the first complete system-on-chip for power line communication.
