CHARACTERISTICS
VDDD = VCCA = VCCO = VCCPLL = 5 V; Tamb = 25 °C; input signal Yext/CVBS = 1 V (p-p) (0 dB); input signal
C = 0.7 V (p-p) (0 dB); input signal FSC = 200 mV (p-p), sine wave, DC level = 2 V; input signal LPFION = 5 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 CVBSO, YO, CO = 1 kΩ and 20 pF in parallel; unless otherwise
specified.
