RSET
A resistor (RSET) connected between this pin and GND controls the magnitude of the full-scale video
signal. Note that the IRE relationships are maintained, regardless of the full-scale output current. The
relationship between RSET and the full-scale output current on IOG (assuming ISYNC is connected to IOG)
is given by:
RSET (Ω) = 11,ꢀꢀꢁ × VREF (V)/IOG (mA)
The relationship between RSET and the full-scale output current on IOR, IOG, and IOB is given by:
IOG (mA) = 11,ꢀꢀꢀ.8 × VREF (V)/RSET (Ω) (SYNC being asserted)
IOR, IOB (mA) = 7989.6 × VREF (V)/RSET (Ω)
The equation for IOG is the same as that for IOR and IOB when SYNC is not being used, that is, SYNC
tied permanently low.

PSAVE
Power Save Control Pin. Reduced power consumption is available on the ADV712ꢁ when this pin is
active.
ꢀ9 (EPAD)
EP (EPAD)
The LFCSP_VQ has an exposed paddle that must be connected to GND.
