Sometimes, being good just isn’t good enough. Even if a sports team is winning all of their games, the coach still schedules extra practices so they can play even better. Race car drivers always seem to need more speed, parents definitely need more time, and Tim Taylor wants “more power.” And Breathless Mahoney? She just wants – More.
This same drive for improvement can be found in a number of imaging applications, such as surveillance, intelligent transportations systems, and medical imaging. While the imaging system currently being used might be “good,” there’s always a need to push performance to a higher level – more frame rate, more dynamic range, more light sensitivity – to allow critical images to be captured under even more challenging conditions.
Sometime, you just need more.
As an example, think about the TRUESENSE 5.5-micron Interline Transfer CCD Portfolio. This family of image sensors, ranging from 1 to 29 megapixel resolution, has been widely adopted across a number of applications because of their high performance, high dynamic range, and excellent smear rejection. But as good as they are, there’s always someone – or some application – that can benefit from an even higher level of performance.
That’s why last year we announced the KAI-16070 Image Sensor, the first device in the TRUESENSE 7.4-micron Interline Transfer CCD Portfolio. And today, we’ve expanded this family with two new devices – the 1080p resolution KAI-02170 and 4 megapixel KAI-04070 Image Sensors.
All of these image sensors leverage the underlying architecture of the 5.5-micron family into larger, 7.4-micron pixels to provide superior performance for use in the most demanding imaging applications. A new output design allows charge packets to be sampled twice – once at high gain, once at low – to extend the linear dynamic range available from these products up to 82 dB when pixels are binned. And the devices are compatible with the existing 5.5-micron product family, so camera manufacturers can directly leverage existing camera designs to support the new products.
Compared to the 5.5-micron family, these new products provide more: more sensitivity, more smear rejection, and more dynamic range – all in a pin-compatible design. (And compared to the prior generation of 7.4-micron devices, they provide a lot more, including a doubling of frame rate compared to the KAI-2093, KAI-04022, and KAI-16000.) With these improvements, this family of image sensors sets a new bar for image quality, allowing critical details of an image to be captured even when it’s not possible to fully control lighting.
Sometimes asking for more can seem greedy. But sometimes, it turns out that more is exactly what you need.

Cliff:
I talked to one of our Application Engineers, and he said that Analog devices has a series of AFE’s that work well with our products. We have done reference designs based on both the AD9920 and AD9928, and are now working with the ADDI7015. Depending on the type of camera design you are implementing you may find that one AFE fits your design goals better than another.
You can find out more information about Analog devices AFE on their Camera/Camcorder Analog Front Ends page located at http://www.analog.com/en/audiovideo-products/cameracamcorder-analog-front-ends/products/index.html
TI also has AFE offerings, but to date we have not had the opportunity to evaluate them. -
Tuesday, 23 October 2012Hi Michael,
Would you know who to contact about acquiring samples/dev kits for these image sensors?
Thanks -

Carson:
Best path is to send us a note at info@truesenseimaging.com - I'll forward your contact information to our customer service team (who monitors that mailbox) and have someone get back to you.
Hi, Michael: Do you have recommended AFE to go with your latest CCD sensors?
Thanks,
Cliff
