Other Parts Discussed in Thread: LMH0040, LMH0340

Please let me know about whether LMH0340 and LMH0040 can use below function.

①Over the 1920×1080 60i

②RGB, YCbCr 4:4:4, and YCbCr 4:2:2

③Color conversion： RGB⇒YCbCr 4:2:2

④SDI superimpose with the sound(vioce)

Greetings Satoshi-San,
LMH0340/LMH0040 uses FPGA to generate different video frame format. I believe the present FPGA IP supports items 1,3, and 4. I am not sure about YCbCr 4:4:4. Customers use present FPGA IP and add additional features like 4:4:4 support. Please below note a link and documentation for FPGA IP features:

Thank you for reply.

Sorry for additional question about ④, can LMH0340/LMH0040 use I2S to SDI?
(External I2S input ⇒ superimpose ⇒SDI output)

If LMH0340/LMH0040 can use, is there information (Application note) of I2S⇒SDI interface?
If LMH0340/LMH0040 can't use, is there have matching device?

Best regards,
Satoshi

Satoshi-San,

I2S input normally goes to the FPGA. Then FPGA IP converts I2S audio to ancillary data for SDI frame. In summary, FPGA IP takes care of the I2S data.
