Dear Analog Devices Team
We are designing a board which uses ADV7391BCPZ Video Encoder and ADA4433-1BCPZ-R2 SD Video filter amplifier.
Below are the few observation :
it is clear for the COMP and Rset connection on the ADV739X datasheet pin definition:
RSET Controls the amplitudes of the DAC 1, DAC 2, and DAC 3 outputs. For full-drive operation (for example, into a 37.5 Ω load), a 510 Ω resistor must be connected from RSET to AGND. For low-drive operation (for example, into a 300 Ω load), a 4.12 kΩ resistor must be connected from RSET to AGND
COMP Compensation Pin. Connect a 2.2 nF capacitor from COMP to VAA;
The ADV739x contains three DACs. All three DACs can be configured to operate in full-drive mode. Full-drive mode is defined as 34.7 mA full-scale current into a 37.5 Ω load, RL. Full drive is the recommended mode of operation for the DACs.
Alternatively, all three DACs can be configured to operate in low-drive mode. Low-drive mode is defined as 4.33 mA full-scale current into a 300 Ω load, RL.
The ADV739x contains an RSET pin. A resistor connected between the RSET pin and AGND is used to control the full-scale output current and, therefore, the output voltage levels of DAC 1, DAC 2, and DAC 3. For full-drive operation, RSET must have a value of 510 Ω and RL must have a value of 37.5 Ω. For low-drive opera-tion, RSET must have a value of 4.12 kΩ, and RL must have a value of 300 Ω. The resistor connected to the RSET pin should have a 1% tolerance.
The ADV739x contains a compensation pin, COMP. A 2.2 nF compensation capacitor should be connected from the COMP pin to VAA.
Also you can see the reference schematics design on ADV739X datasheet Rev E page 72 and &3, Fig- 93 and 94;
