NOTES: A. All values are in Ω and µF unless otherwise noted.
B. TI recommends ac coupled system for coupling to the next video processing circuits.
C. IAG and SAG signal from user defined timer must be shifted its GND level to –V before the driver IC (EL7156CS) input.
D. The value of the CCD external capacitors (on IAG and SAG) were recommended with 2000 pF ~ 5000 pF.
