SCAN926260: Replacement for SN65LV1224

Part Number: SCAN926260
Other Parts Discussed in Thread: SN65LV1023A, SN65LV1224B

Hello,

IS 6 channel SCAN926260 deserializer with has the same functionality as SN65LV1224 + JTAG feature to test LVDS input? 

In my system there is 8 image sensor, each of them is streaming video data thorough single  LVDS line. Then this LVDS data is deserialized by eight SN65LV1224 chip to the FPGA.

If this would be possible to replace 8 pcs. of  single channel by only 2 pcs. of hexa channel deserializer than it can reduce overall system part count, price, EMI issues and other things.

    Hi Remigijus,

    What is the clock frequency of your application?

    If it is within 16-66 MHz, then you can use the SCAN926260. This device is a companion deserializer to the DS92LV1023 (similar device to the SN65LV1023). Since the SN65LV1224 is a companion deserializer to the SN65LV1023. the SCAN926260 can also serve as a companion deserializer.

    Regards,

    Hello Michael,

    thanks for the answer.

    I using 27MHz MEMS clock oscillator and it is in the same range: 16-66MHz. Is any development kit for this series deserializers (can be 6 channel or single channel)? 

    So I keep forward to replace with SCAN series part in my application design.

    P.S. All You mention part number is already NRND. As I understand TI changes all deserializer from SN65 to DS92 (this is some kind of legacy which came from National Semiconductor part number system)?

    Hi Remigijus,

    Unfortunately, since this device is a legacy device, we do not have development kits available for this deserializer.

    The SN65LV1023/SN65LV1224 and DS92LV1023/DS92LV1224 are slightly different devices performing identical functions. One is from TI (starting with SN) and the other is inherited from National Semiconductor (starting with DS). The active versions of them are as follows, with slightly different supported clock frequency ranges, but this should not impact your need to support a 27 MHz clock:

    - SN65LV1023A

    - SN65LV1224B

    - DS92LV1023E

    - DS92LV1224

    Thanks,

    Michael
