Start with the news release ADSL module for small production quantities from Insys Microelectronics, which we summarised at the time by saying "Insys Microelectronics has brought out the QLM-A100 Quick Line Module, a compact ADSL module with a connector concept suitable for industrial use, enabling batch integration for the first time.". Several months prior to that, we featured the news release Kenton launches LIU202A broadband line isolator from Kenton Research: "Kenton Research has launched the LIU202A broadband line isolator, which provides 15KV RMS of galvanic isolation on transmission lines with DSL/broadband services and active equipment.".
 
In December 2009, we covered the news from Intersil - take a look at Line driver supports 8MHz and 17MHz VDSL2 profiles which says: "Intersil has introduced the ISL1539A: the latest addition to its range of DSL line drivers for the VDSL2 ultra-high bit rate internet connectivity standard.".
 
Take a look also at the news release from Infineon Technologies, Xway Wave100 ICs comply with 802.11n , as well as Trend releases Multipro Copper 6MHz from Trend Communications, and Trend improves the MC2+ ADSL tester from Trend Communications.
