Re: sb6141, sb6180, zoom5341, dpc3010

said by Thordrune:

There's another difference as well, something that intrigues me: the 3010 has two RF tuners, whereas the 3008 uses a single tuner. I wonder what benefits/differences using two tuners presents in real-world conditions.

Actually, from what I can tell, it looks like the DPC3010 uses the older "first generation" DOCSIS 3.0 Broadcom BCM3380 chipset with its "Integrated 64-MHz wideband receiver with two independent 32-MHz blocks" (»www.broadcom.com/product ··· /BCM3380 and »datasheet.elcodis.com/pd ··· fsbg.pdf) while the DPC3008 uses the "second generation" BCM3382 chipset with its "second generation integrated wideband tuner, with an extended bandwidth of 96MHz" (»www.broadcom.com/product ··· /BCM3382).

From the press release for the BCM3382 (»www.broadcom.com/press/r ··· =s434809 ):

"... the new single-chip Broadcom BCM3382 solution improves RF performance with its second generation of integrated tuners ..."

So it looks like the DPC3008 modem is the later model of the two in that it uses the newer Broadcom BM3382 chipset.

Also, the data sheet for the DPC3010 says "Copyright 2009-2010" and dated "November 2010," while the one for the DPC3008 is "Copyright 2010, 2012" and dated "August 2012."

Ah, that makes sense now. I didn't even notice the dates on the info sheets . I was seeing the dual tuner/32 MHz part on the 3010 and wondering why it was narrower overall than the 3008.

Strange that I heard about the 3010 way after the 3008, I guess it wasn't a popular model. Mediacom seems to really like the DPC3000, and I was wanting to get something a bit newer, so maybe it'll be the 3008 then.

One thing I forgot to mention about the DPC3008 is that there is a thread on the Comcast Help and Support Forum about an issue with frequent disconnects that many people have had with that modem: »forums.comcast.com/t5/Co ··· /1254989

However, according to the latest posts in that thread, it looks like a recent update to a May 2012 version of the firmware may have resolved the issue.

The Zoom 5341j also uses that newer Broadcom BCM3382 chipset also.See this »Zoom 5341G (4x4) vs Zoom 5341J (8x4)

Yes, and as was said in this thread »Re: [Connectivity] Mototola SB 6141 , I think the choice of good 8x4 modems right now comes down to either the (well regarded) Zoom 5341J or the (currently well reviewed) Motorola SB6141, with the TI/Intel Puma 5 TNETC4840 chipset.

Also, there should be a new generation of modems released soon incorporating Intel's next generation "Puma 6" chipset: »www.lightreading.com/blo ··· d=218885 and »www.lightreading.com/doc ··· d=220955
