CHARACTERISTICS
VDDD = VCCA = VCCO = VCCPLL = 5 V; Tamb = 25 °C; input signal Yext/CVBS = 1 V (p-p) (0 dB); input signal
Cext = 0.7 V (p-p) (0 dB); input signal FSC = 200 mV (p-p), sine wave, DC level = 2 V; test signal: EBU colour bar
100/0/75/0 “CCIR471-1”; source impedance for Yext, CVBS, Cext = 75 Ω decoupled with 100 nF; source impedance for
FSC = 75 Ω; load impedance for YO, CO = 1 kΩ and 20 pF in parallel; see Fig.9; unless otherwise specified.
