ADV7842 Electrical specs

Hi,

 

I'm looking to do a timing diagram to check the buses connecting the ADV7842 to other IC's on my board.

Are there AC electrical specs (timings) for the pixel port outputs and the I2S bus that i could use? (e.g. llc clock to data and sync signal delays, etc)

 

secondly i've noticed a few differences between the datasheet and the eval board for the test pins.

could you confirm what the correct connection mode is?

 

 

ADV7842_HW_Manual_RevA_23_December_2010:
Table 1;
C11 Test8 Test pin Tie to 3.3V via 4.7k resistor
N4 TEST4 Test Connect this pin to ground.
P3 TEST5 Test Connect this pin to ground.
Table 100;
C11 Test8 Test pin Tie to 3.3V via 4.7k resistor
N4 TEST4 Test This pin should be tied to ground.
P3 TEST5 Test Float this pin
Evaluation schematics (PAVPipe V1.0 8/12/2010):
C11 PWRDN2#  Tied to gnd via 4.7k resistor
N4 TEST4 Floating
P3 TEST5 Floating

 

many thanks,

stu
