CHARACTERISTICS
VCCA = VDDD = 5 V; 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: 100/0/75/0 EBU colour bar for PAL B, G, H, D, I and N, 100% white 75% amplitude FCC colour bar for NTSC M
and PAL M; source impedance for Y/CVBS1 and Y/CVBS2 = 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 specified.
