Hi
Characteristics of ADV7802 and ADV7188 by INL, DNL, DP, DG, LNL are close. But ADV7842 's INL is noticeably worse - why?
The rest of the listed characteristics for ADV7842 are slightly worse - why?
ADV7842 ADV7802 ADV7188
INL at BSL=54 MHz [LSB] (at a 12-bit level) −3.0 to +8.0 (at a 12-bit level) −1.5/+2.0 −1.5/+2.5 (±8 max)
INL at BSL=108 MHz[LSB] (at a 11-bit level) −3.5 to +8.0 (at a 10-bit level) −0.8/+2.0
Differential Phase [deg] 0.6 0.45 0.4
Differential Gain [%] 0.8 0.45 0.4
Luma Nonlinearity [%] 0.9 0.7 0.4
Chroma Amplitude Error [%] 0.9 0.4 0.4

Hi,
These specifications related details are need to discuss with part specialist/Experts. But ADV7842 is a new design and It's going to be much easier to get support on and also the eval board which is very easily (and cheaply) available for it.
Thanks,

Hi, Poornima
Thanks for the answer.
This was surprising - despite the fact that ADV7842 is newer than ADV7802, its characteristics by INL, DP, DG, LNL, CAE in DataSheet are worse...ADV7850 has similar INL, DP, etc. (in DataSheet) as in ADV7842.
