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.
Note4) DAC ON, Video Amp On SAG Compensation On
Note5) DAC ON, Video Amp Off (SAG Compensation Off)
Note6) DAC Off, Video Amp Off (SAG Compensation Off)
