[Connectivity] Dual 32 MHz vs Single/Dual 96 MHz Tuner?
Is there any difference between modems using either? Is one better? One worse?
Re: [Connectivity] Dual 32 MHz vs single 96 MHz Tuner?
Well, if you're talking Broadcom DOCSIS 3.0 chipsets:
The "first generation" Broadcom BCM3380 chipset used an "Integrated 64-MHz wideband receiver with two independent 32-MHz blocks." (»www.broadcom.com/products/Cable/···/BCM3380)
The next, "new and improved" Broadcom BCM3382 chipset used "a second generation integrated wideband tuner, with an extended bandwidth of 96MHz." (»www.broadcom.com/products/Cable/···/BCM3382)
So it's better to have a "single 96 MHz tuner" in your modem.
Is the DPC3008 still having issues on the newest build they released? Anyone hear of the problems occurring on a Cisco CMTS?
The Comcast thread seemed to have settled down lately.
According to the latest reports I've seen on the DPC3008, it looks like the update to the May 2012 version of the firmware may have resolved the issues.

Thanks Telco for your responses . I always like how you leave links to things on your posts and keep things updated.
Well, I ordered the DPC3008 right now. I had the SB6141 ordered but $40 more wasn't worth it to me lol. If it doesn't work right then I guess I can always send it back :P.

I have the DPC3008 and do pretty heavy usage in both directions and I havent had a single issue. I am on the new May 2012 firmware as well. When I bought it, it had the older firmware, but it auto updated itself when I hooked it up.
What are your signals like? Since getting the DPC3008 my power levels went from 1.6-3.3 to 3.2-6.7 dBmV and SNR went from 35-38 to 40
