To USB or Not to USB


Synopsys USB 3.0 Success Story – Realtek

We have a new Success Story from Realtek with our USB 3.0 digital IP.

Using DesignWare USB 3.0 IP, Realtek achieved first-silicon success for their industry’s first certified USB 3.0 card reader.  So read the Success Story here talking about the integration of our USB 3.0 Device into the Realtek design.

I think this might still be the ONLY USB 3.0 Card Reader chip in the whole universe. I’ve looked for another one and I can’t find it.

If find or know of another USB 3.0 Card Reader, send me an e-mail, or Twitter use at #SNPS.

As you know from reading blogs, these faster USB 3.0 Card Readers are critical for reading faster SDXC flash chards that read data at 95 Megabytes or 0.95 Gigabits per second.  This is much faster than the speeds that USB 2.0 can deliver (USB 2.0 typical effective throughput is about 32 Megabytes per second).  Scroll down to the SD section in this blog entry for more on SDXC which will will allow read speeds of up to 3 Gigabits per second.  (The new MacBook Air and Pro have SDXC card readers. I’m guessing these use a USB 3.0 Card Reader.


Here’s a picture of a USB 3.0 Hub combined with the Realtek Card Reader chip the RTS5182.

You may have known that Realtek is our customer for our USB 3.0 digital IP including USB 3.0 Host and Device from our 40 design wins, 30 customer press release.  We thought you’d like to hear/read what the engineers said about our IP.



Response to Reader Comment – Digital Camera Story

I received the following comment on my Why the iPhone 4S drives the need for USB 3.0 blog

youre an idiot if you think that any fixed lens camera (like the iphone 4s) will replace a mid-ranged digital camera.


You can read my formal response below


But first, here is some evidence I am not an idiot.  I visited the Mall of America.  It has an Amusement park.  I looked over at 2 park benches with six adults.

This is what I saw from left to right

Person 1) Digital SLR taking a picture

Person 2) SmartPhone taking a picture

Person 3) SmartPhone taking a picture

Person 4) SmartPhone taking a picture

Person 5) SmartPhone taking a picture

Person 6) SmartPhone typing on their SmartPhone


This is the Mall of America in Minnesota. This is the MidWest or Central U.S.

Many of the visitors are from the midwest, like Colorado or Michigan. (This is my unofficial sampling of the people in the park)

My point:  The SmartPhone has already replaced most cameras.

(I would have taken a picture of this scene with my SmartPhone, but It didn’t occur to me until after everyone had put down their phones.)

My other response is below.

I would like to say first:

1) Thanks for calling me an idiot. It’s refreshing.

2) How many people actually carry around a camera, who carry an iPhone 4S?
ANSWER: Probably not a lot.

3) Do Mid-Range cameras and Pro-sumer cameras become only Special Event cameras?
ANSWER: Yes. Maybe only the 1 Dad or 1 Mom or serious photographer. Otherwise, the iPhone 4S camera is “good enough” for recording all but the most important events that require either HD or high speed photography.

4) Where do you carry a low-end or mid-range camera?
ANSWER: Markets where SmartPhones are not affordable or accepted. In this case, the low-end phones will always have USB 2.0. And the user has to have a PC to connect them to, and the knowledge to upload them, and the time, and if they have all those things, do they have the money for a SmartPhone? If they have the money for a Smartphone do they have a dataplan? If they have a dataplan, why wouldn’t they take the picture with their 8MP iPhone 4S?
The point is: The mid-range camera is for the person that is sophisticated enough to own a smart phone, but either can’t afford either a smart phone, a data plan, or a pro-sumer phone.
I’m open to counter arguments here.
