DS92LV2421: need a recommend suitable product

Prodigy 40 points

Part Number: DS92LV2421
Other Parts Discussed in Thread: DS90UB947-Q1, DS90UB948-Q1

we are plainning to make a LCD display board.

Fiber optic --> interface board --> 51PIN LVDS on the EIA-644 Standard.

Can you recommned Serializer and Deserializer?

I would like to develop a bidirectional communication product.

    Hi Taehee,

    1. Could you please input what the input interface of the Serializer input needs to be?

    For example, a typical FPD-Link SerDes configuration may be with the DS90UB925-Q1 (SER) and DS90UB928-Q1 (DES):

    SoC -> RGB/LVCMOS video input -> UB925 -> STP or coax cable -> UB928 -> OLDI/LVDS video input-> Display

    2. What is the optical fiber you are referring to? Is this a coax cable that connects one board with a serializer to another board with the deserializer?

    3. What is the "interface board"?

    Best regards,
    Ikram

    Dear,

    thanks for your feedback.

    My concept are PC->LVDS input ->Fiber Optic(SFP) ->LVDS output ->LCD Display(51PIN on the EIA-644 Standard)

    1. Can you recommend LVDS input IC and LVDS output IC. (need a example schematic)

    2. is it possible to Fiber Optic -> LVDS output (i want to delete FPGA) if it is OK Please let me know how can i it?

    Hi Taehee, 


    LVDS input IC: DS90UB947-Q1
    LVDS output IC: DS90UB948-Q1

    You can find these parts online on TI.com and refer to their EVMs and datasheet schematic for reference.

    The FPD-Link SerDes I mentioned are typically used with shielded-twisted pair or coax cable types. The cable lengths are much shorter as it's used for video transmission within vehicles. The cable length is still dependent on whether the channel (including cable) can meet the channel specifications for IL/RL.

    The FPD-Link SerDes were not tested specifically for optical fiber conversion. 

    Have you previously used any SerDes over this optical fiber and utilized back channel (for bidirectional communication)?

    Best regards,
    Ikram
