Intel's New Docsis 3.0 Chip Guns for 1-Gig

Intel Corp. (Nasdaq: INTC) is coming out with a next-gen Docsis 3.0 chipset that targets maximum speeds of 960 Mbit/s downstream and 320 Mbit/s upstream and has signed Hitron Technologies Inc. as one of the first customers for the silicon.

Intel's been a bit cagey about how many channels its new D3 platform, called the Puma6, can bond. And apparently there's more than one answer. There's a regular version that can bond 16 downstreams and four upstreams and an amped-up MG (media gateway) iteration that can bond 24 downstreams and eight upstreams. Arris Group Inc. (Nasdaq: ARRS) confirmed that it's using the 16x4 Puma6 chipset in a new voice gateway called the TG1672. (See Intel Goes Deeper Inside Docsis 3.0.)

Hitron, one of Intel's Alpha customers, is jumping right to the Puma6MG for the CDA-32372, a stand-alone cable modem that the vendor will be showing off at The Cable Show next week in Boston. The company is also hopeful that a Wi-Fi-capable gateway device might be ready for the event, says Hitron CTO Greg Fisher, noting that the vendor is about two months away from finishing another gateway model, called the CGBV, that also supports cable voice services. Hitron also plans to develop a video gateway that could factor into cable's IP video transition and take full advantage of the Puma6MG. (See Intel's New Set-Top Chip Packs More Punch.)

The Puma6 family represents the first new Docsis 3.0 products to come out of Intel since it bought the cable modem assets of Texas Instruments Inc. (NYSE: TXN) in 2010 and represents a big leap over current state-of-the-art for D3 silicon that's capable of bonding eight downstream channels and four upstream channels. Intel's expected to announce more details about the Puma6 next week. Broadcom Corp. (Nasdaq: BRCM), Intel's chief competition in this area, has yet to announce what's next on its Docsis 3.0 roadmap. (See Intel Snares TI's Cable Modem Business and Broadcom Dips Two Chips in 800M 'Prototype' .)

Intel's 24x8 configuration would get Docsis 3.0 downstream burst speeds within shouting distance of 1Gbit/s (viewed as the next major milestone for Docsis 3.0) when used for the 6MHz-wide channels that North American cable MSOs employ. In EuroDocsis systems, which use wider 8MHz channels, a fully-loaded Puma6MG could pump out downstream speeds bursts of about 1.32Gbit/s.

Hitron's strategic decision
Fisher says Hitron is skipping over 16x4 because the vendor believes the configuration will represent a "footnote in the history of Docsis" and have a relatively short market window of nine to 12 months. And Fisher's drawing on some recent history, recalling that Texas Instruments entered the Docsis 3.0 market with a 4x4 chip, only to see Broadcom blow by it with an 8x4 version.

"We thought the same thing would be likely with the 24x8," Fisher says, noting that the price on the Puma6MG isn't terribly more expensive than the 16x4 chip. He says of at least one MSO "has pretty firm plans" to be ready to bond 16 downstream channels by the end of 2012, and to be positioned to bond 20 to 24 by the end of 2013.

But Hitron has yet another reason to max out. It's trying to make some noise in the market as its resets its sales strategy for North American cable. Hitron has historically served as an OEM for cable gear vendor SMC Networks Inc. , but it will now try to sell directly to MSOs and mirror the model it's using in Europe and Asia. (Fisher and Hitron Chief Sales and Marketing Officer Todd Babic are former SMC execs who joined Hitron last fall, by the way.)

And Hitron is making some progress; Babic says Hitron is about to launch product with one North American MSO and is in certification with at least three others.

The vendor hopes to have its new stand-alone D3 modem ready for general availability by this August or September, with the data gateway to follow in September or October. The timing partly hinges on when Intel is ready to enter mass production on the Puma6, as well as when Hitron can obtain Docsis 3.0 certification from CableLabs . Hitron plans to enter the modem in CableLabs cert wave 93, which gets underway in mid-July, and the gateway in wave 95, slated to start in late September.

intel收购了ti的cm后，一直没看到什么动静，本来指望凭借他的实力，能把cm和编解码做在一起呢。这样docsis技术就有绝对的优势了，不过看来还是难度很大。
现在市面上的互动盒子看的我蛋疼，硕大的盒子。你妹，芯片不能集成，你总可以把板子做一块把。
是人家电信iptv盒子的4倍大。丢人不。

英特尔的新芯片1-Gig枪支Docsis 3.0

英特尔公司(纳斯达克:INTC)是推出一个新一代Docsis 3.0芯片组,目标的最高时速960 Mbit / s下游和320 Mbit / s上游并已签署Hitron技术公司的首批客户之一硅。

英特尔一直讳莫如深多少个通道新D3平台,叫做Puma6,可以债券。显然有一个以上的答案。有一个普通版本,可以downstreams和四个上游债券16和一个带毫克(媒体网关)迭代可以24 downstreams和八个上游债券。棱集团有限公司(纳斯达克:各村证实,它使用了16 x4 Puma6芯片的一个新的叫做TG1672语音网关。(看到英特尔深入内部Docsis 3.0)。

Hitron,英特尔的Alpha客户,跳的权利的Puma6MG CDA - 32372,一个独立的电缆调制解调器,卖方将展示在有线电视节目将于下周在波士顿。该公司还希望登录网关设备可能准备事件,说Hitron首席技术官格雷格•费舍尔指出,该供应商是大约两个月远离完成另一个网关模式——称为“CGBV,还支持有线语音服务。Hitron还计划开发一种视频网关,可以到的因素电缆的IP视频过渡,充分利用Puma6MG。(看到英特尔的新机顶盒芯片包更有效果)。

这翻译的累呀！伤不起

Intel今天披露了业内第一款传输速度可达1Gbps的DOCSIS 3.0标准有线网关方案，基于Intel Puma 6技术，可让网络运营商在维持现有基础架构的前提下，为用户提供更高的带宽和更新的服务，满足高清点播、视频会议、云存储、轻松分享的需求。

DOCSIS全称为Data-Over-Cable Service Interface Specifications，意思是有线电缆数据服务接口规范，是有线电缆标准组织CableLabs制定的一个国际标准，最早的1.0版本诞生于1997年，最新的3.0版本发布于2006年，上行、下行速率分别提高到120Mbps、160Mbps，并支持IPv6。

DOCSIS规范定义了在有线电缆上提供数据服务所需的通信和运营支撑的接口，使得在现有的有线电视系统上进行高速数据通信成为可能。许多有线电视运营商都采用它在现有光纤混合同轴电缆(HFC)的基础设施上提供互联网接入服务。

Intel表示，目前典型的网络部署只能整合最多8个DOCSIS通道，Intel Puma 6技术则将其增加到了24个，下行速率因此高达1Gbps。上行方面仍然是8个通道，但即便如此上行速率也提升到最快240Mbps，是现有DOCSIS Modem的两倍。

韩国互联网供应商SKBroadband将会第一个试验Intel的这套新方案，并计划2013年投入实际运营，用于高清电视、多人游戏、视频会议等等。

Intel上一代的Puma 5技术曾率先实现了DOCSIS 3.0。迄今为止，基于DOCSIS 3.0的系统已经全球出货了200多万套。

目前业界只有 CASA SYSTEMS的CMTS 才能支持高于32下行通道捆绑输出，所以说验证Intel的终端能达1Gbps 也要有好的头端才行啊............:victory:
