Title: VDSL2 chipsets
Post by: asbokid on July 28, 2012, 12:34:56 AM

I was going to add this to the Kitz Wiki but am not authorised. Guess it will have to wait until I'm older, unless a responsible adult will add it on my behalf? :D


There are surprisingly few VDSL2 chipsets available today; just a handful of commercially-available chipset choices for CPE:

• Broadcom's market-leading VDSL2 SoC, the ubiquitous BCM6368. This solution is found in the Huawei HG612, the Alcatel Cellpipe 7130, the ZTE ZXDSL931CII and the ZyXEL P-2812HNU-51c, to name a few. [1]
  
  
• Lantiq, the Munich-based fabless chipmaker, produces the VR9 (VRX200) family of VDSL2 SoC. [2] Taiwanese CPE maker, Arcadyan, powers several models of modem-router by the VRX288 from this SoC family.  The VRX268, another VR9 SoC, drives the ECI B-FoCuS, the alternative VDSL2 CPE used by BT Openreach, The VR9 SoC is also used in newer models of the AVM FRITZ!Box, e.g. the 7360.
  
  
• Ikanos (was Conexant) offers the Accelity, its first VDSL2 CPE chipset. The Accelity is a two IC solution, comprising the DA87781 VDSL2 analog front end (AFE) / line driver (LD), coupled to a BA6-7779 for digital signal processing. The Accelity is found in the 2Wire/Pace VDSL2 Residential Gateways, e.g. the 3600HGV and 3800HGV [3]
  
  
• Ikanos has another VDSL2 CPE chipset series: the Fusiv Vx180/185. This is a single chip solution.  The Vx180 is found in some D-Link devices, e.g. the DSL-6641K, and some models of FRITZ!Box, e.g. the 7390. [4]
  
  
• PMC-Sierra, the Malaysian chipmaker, launched its own VDSL2 offering, the PM4380, an AFE/LD. This IC is found in newer VDSL2 CPE supplied by AT&T and other N.American carriers (e.g. the Uverse 3801HGV). [5]
  
  
• Metanoia Comms, a Taiwanese tiddler, launched Jan 2012 its two chip VDSL2 PHY solution, the Merlin VDSL2 chipset. [6]  Comprising an AFE (MT3301) and a DSP (MT2301), it is reportedly already in use in the latest Draytek VDSL2 models, e.g. the Vigor 2850n [7]
  
  
• Mediatek (was Ralink, who swallowed up TrendChip in 2010) was on the brink of launching its own VDSL2 CPE chipset - the RT65168. However, Mediatek seems to have scuttled those plans. [8]

An excellent review. Thank you for posting it.

I guess that Senior Management ^[1] will be checking with the courts, regarding your "sentence" and when you will be free of your "ankle bracelet", before giving you write access to the WIki.  ;)  After all, those who have spent some time creating its current content wouldn't be too happy to know that your Wayne (having learn the art of forgery from "Big Boris" of Parkhurst) might enter using your ID, whilst wielding an aerosol can of Chav-paint!  :-X  ::)  :P

CRB checks completed. Asbo should be in receipt of an email. :)

Good post and info, thanks Asbo.

Re the wiki, we decided to make it content team only as if left open (or even to registered users) wikis seem to attract many spambots, and even abuse.   This type of spam/abuse is harder to spot than on forums and may not be discovered for a while.    Any of the forum regs that would like to be part of the content team is more than welcome to apply :)

Thanks Guys - email received!  The wiki sandbox here we come then, until I find my feet. Hold your noses: shoes and socks off to let off some steam!
