XC-ST70/70CE PHASE CONDITIONS OF EXTERNAL SYNCHRONIZATION External synchronization for each mode • For normal video/normal shutter Continuous HD/VD signal (should conform to EIA and CCIR frequencies in the timing shown in the figure below.) • For Restart Reset (RR)/external trigger shutter Continuous HD signal. The phase between VD (reset) and HD signals is as specified in the figure below in any timing. Phase conditions The phase relation between external input HD and VD signals should be set as shown below with respect to the specified center phase. EXT-VD ODD (EVEN) EVEN (ODD) 100 200 5 200 EXT-HD 455 (454) 455 (454) The operation in parentheses refers to XC-ST70CE. Unit: Clock 1 CLK = 69.84 n sec (XC-ST70) = 70.48 n sec (XC-ST70CE) Note : The synchronized VD signals are delayed for 1H at HD/VD external synchronization mode, while there is no VD signal delay at VS external synchronization mode. 6
