Powerline Comm Modem Selection

Greetings,

I am designing a PLC application, and I need a reliable modem for this (IC, not modules, as it will be integrated in small devices). I have studied the Yitran IT700, MAXIMs MAX29xx, NXP TDA5051, LM2893 and ST75xx until now.
I was tempted to go with ST7540, but I saw some negative opinions on this forum.

Does anybody have any experience with IT700 ? Is it really worth the price (I saw it at something like 11 USD in 100 pieces) over the simple TDA5051 (at about 4 USD) ? Besides higher speed, is the "smart" part of the IT700 really as good as the datasheet says ? Does it free the software from every network related task, including collision avoidance ? Does it allow communications initiated by slave devices ? Is it reliable ?

Also, with TDA5051, can somebody offer any opinions ? Maybe regarding communication reliability. Is it possible to implement some kind of collision detection on this, to allow slaves to initialize communication ? My guess is no..

I am also free to suggestions, for other ICs.


Thank you in advance for your time!

Hi Alin,

My name is Yaniv from Yamar electronics. It looks like our SIG60 device is a perfect solution for your application. The SIG60, interface directly with any uc using UART interface (upto 115.2Kbps), acting as a transparent transceiver. It can be a part of a network and was designed to operate on noisy powerlines such as in automotive environment. You can check our PLC solution at www.yamar.com
P.S - The price is about half for 100pcs

Best regards
