EXTERNAL LOOP FILTER
LOOP FILTER COMPONENTS
SHOULD BE LOCATED
CLOSE TO THE EXT_LF
PIN AND ON THE
SAME SIDE OF THE PCB
AS THE ADV7390.
NOTES
1. FOR OPTIMUM PERFORMANCE, EXTERNAL COMPONENTS CONNECTED
 TO THE COMP, R
SET
 AND DAC OUTPUT PINS SHOULD BE LOCATED
 CLOSE TO, AND ON THE SAME SIDE OF THE PCB AS, THE ADV7390.
2. THE I

C DEVICE ADDRESS IS CONFIGURABLE USING THE ALSB PIN:
 ALSB = 0, I
2
C DEVICE ADDRESS = 0xD4
 ALSB = 1, I

C DEVICE ADDRESS = 0xD6
3. THE RESISTOR CONNECTED TO THE R
SET
PIN SHOULD HAVE A 1%
 TOLERANCE.
4. THE RECOMMENDED MODE OF OPERATION FOR THE DACs IS FULL-
