Need a suitable IC which meets my requirement of switching between two video inputs.

Hi,

   All our video decoders are single video channel parts and there is only one output bus so we would need 2 ADV part to process two inputs simultaneously similarly for 3 channels, we would need 3 ADV parts. 

   Please note that "ADI does not have a chip that can handle multiple video streams at the same time.

   As far as all analog video decoders can only select (and thus output) one stream at a time.

   If a project requires multiple video streams simultaneously, they will need multiple video decoder parts.

Thanks,

Hi,

From the AD site, i have gone through few Chips, please confirm whether those chips will meet my requirement or not

Req 1. Two PAL video inputs by selection gives out one PAL video output.

Chip found: MAX4649 which has selection between two inputs and gives out any one

Req 2. One PAL video input, which should split into four PAL video outputs.

Chip found: ADA4304-4 which takes one input and splits into four outputs

Req 3. One HD-SDI video input which should split into two HD-SDI video outputs.

Chip found: This is from TI LMH0307 which takes one input and splits into two outputs.

please go through the above mentioned part numbers and give your suggestion on those chips, whether it suits my requirement or not.

Hi,

 Please find the below comments,

Req 1. Two PAL video inputs by selection gives out one PAL video output.

  By referring this respective technical document at Download PDF, this part can support two PAL video inputs and one output.

Req 2. One PAL video input, which should split into four PAL video outputs.

     Yes,ADA4304-3/ADA4304-4 provide a single-ended input and three or four single-ended outputs

Req 3. One HD-SDI video input which should split into two HD-SDI video outputs.

     LMH0307 seems 3 Gbps HD/SD SDI Dual Output Cable driver and we got this document from google search LMH0307 3 Gbps HD/SD SDI Dual Output Cable Driver with Cable Detect datasheet (Rev. I) (ti.com)
