Note1) operation at 27 MHz, NTSC mode on-chip 75% color bar output is enabled and Video Amp output is “ on “ ( no  
external output loads are connected except for recommended components. ). 15pF capacitors in following figure represent

Note2) measuring conditions :  
input / output settings after power-down sequence are, PDN pin is at GND level, CLKOUT and SDO output are at high  
level ( power supply voltage ) with no external connection, input voltage on those input pins is 1/2 level of power supply  
which are set to accept Hi-Z input at power-down, and TEST = ATPG = GND ( or left open ).  
Power supplies are AVDD = DVSS = PVDD.  
Each ground pin ( DVSS, AVSS, PVSS ) is always 0 V ( voltage reference ).  
Note3) Operation at 27 MHz, NTSC mode on-chip 75% color bar output is enabled.
