CHARACTERISTICS

VCCA =VDDD =5V; Tamb =25 °C; input signal Y/CVBS1 = 1 V (p-p); input signal Y/CVBS2 = 1 V (p-p); input signal

CIN = 0.7 V (p-p); input signal FSC = 200 mV (p-p) sine wave at fSC; input signal SC = 5 V (p-p) sandcastle signal; test

signal: 100% white 75% amplitude FCC colour bar; source impedance for Y/CVBS1 and Y/CVBS = 75 Ω; coupled with

10 nF; source impedance for CIN and FSC = 75 Ω; coupled with 100 nF; load impedance for CVBS/YOUT and

COUT = 15 pF to analog ground (pin AGND); all voltages are related to analog ground (pin AGND); unless otherwise
