Part Number: DDC2256A Hi TI’s expert,
I am now using 4-DDC2256A along with Xilinx Artix-7 FPGA for CT detector developing. I had several questions when I layout the PCB.
Q1: How do we connect to the differential clock inputs (CLK) and CONV of the…
Part Number: DDC2256A Hello,
I want to develop a compact digital readout circuit for two DDC2256A devices.
I've already inspected the DDC2256EVM and designed an analog circuit with our sensors and two DDC2256A devices which can be read out using the digital…
Part Number: DDC2256A Hi,
Is there a problem with the definition of DDC2256 data manual? (As shown in the figure)
0x10 [5:4] is 2 bits, and the following description is 3 bits.
Thanks!
Part Number: DDC2256A I am developing 32-slice Medical CT with DDC2256, I want to ask, Is there any performance difference in different integration time when we do the offset correction.
Part Number: DDC2256A Hi, I am not successful in writing and reading the registers of the DDC2256A. As I understood
EVERY write must be preceded by a RESET signal. This reset resets the internal state machine of the chip, but also sets the default values…
Part Number: DDC2256A Hello,
I am working with this device and am able to see data when the ADC is commanded to output the pre-defined patterns (all zeros, all ones, ramp, etc).
When I try to collect actual live data, I am not seeing the data change.…
Hey Paul,
Thanks for reaching out! I'm currently looking into possible answers for your questions. In the meantime, I would recommend taking a look at the DDC2256A as a possible candidate due to your channel count requirement. You can request access to…
Other Parts Discussed in Thread: DDC2256A , DDC264 Hello everyone.
I'd like to use DDC2256A (Analog-to-Digital Converter). It has 256 channels and the maximum data rate = 17 KSPS
I was wondering, 256 channels and 17 KSPS here mean that If I use all of…
Part Number: DDC2256A In table on page 32 of the April 2016 datasheet, register 0x3A[6] indicates FCLK output will be an LVDS output when set to 1; otherwise, when set to a 0, the output will be CMOS.
On page 24 section 8.3.9, however, the datasheet states…
