Part Number: LM9833
While looking through the datasheet of the LM9833, it says that it is "compatible with a wide range of color linear CCDs and Contact Image Sensors (CIS)." However, the datasheet doesn't list what qualities/parameters of the LM9833 determine compatibility with CIS modules.
I was wondering:
1) What criteria I should be looking at to determine whether a CIS is compatible with the LM9833 or not
2) In particular if the the FR12F-J03 Canon CIS (datasheet here) is compatible with the chip.
I am moving your post to the Imaging AFE forum where the device LM9833 is supported.
In reply to Praveen Aroul:
The LM9833 could work with that sensor. Key parameters to consider are the necessary sample rate (4 MHz) and the ability to capture CIS waveforms with pixel counts up to 10296.
The LM9833 can sample a single input at up to 6 MSPS and can support line lengths up to 16383.
However the LM9833 is a highly integrated device intended to provide a complete scanning solution from sensor to USB1.1 interface. This level of integration makes the device challenging to design around and the USB1.1 interface will limit data throughput.
A better choice would be the LM98714. This also has the needed capabilities to support that sensor, and when interface to an FPGA or other data processing device can give much better data throughput.
Please take a look at the LM98714 datasheet and see if it will meet your needs.

In reply to Isaac Fenta:
Support for this device is very limited.
I am attaching all of the hardware and software (Windows 9x based) support information I am aware of.
This information is provided as-is.
This device was released a long time and and those involved in the original hardware/software/firmware development at National Semiconductor are no longer available.
First thank you for the files you provided me for the LM9833; it was really helpful. I have a few questions on this:
1. How do I program the LM9833 to control the lights, motors and output.
2. In the schematic, there are circles drawn around different components. What does that represent?
3. Do you happen to have a BOM for the schematic provided? I want to make sure the HDR and J components are just header pins used to test.
Also, asking again about the LM98714, do you have other chipsets that go along with this to make a complete solution similar to the LM9833? If the LM9833 is really old, I don't want to incorporate it into a product and then a few years later it won't be a chip you can purchase anymore. I want to cover all my bases to make sure I get the right chipset for my solution. I need to be able to scan a document at about 8ppm and the chipset should send out a .png file to my computer.
