1. Electrical Characteristics
MS0549-E-02
Digital Input / Output DC Characteristics
( note ) Operation under a condition exceeding above limits may cause permanent damage to the device. Normal operation
is not guaranteed under the above, extreme conditions.
Recommended Operating Conditions
Analog Characteristics and Power Dissipation ( AVDD = 3.0V, DVDD = IVDD = IIC_VDD = 1.8V, Ta= 25°C )
note 1 ) operation at HD DAC : 148 MHz, SD DAC : 27 MHz
note 2 ) Output Bandwidth 30 MHz : at 148 MHz operation, HDY ( load resistor at 150 ohms ) channel only, external load
capacitance ( TBD pF )
note 3 ) variation when a 700 mV equivalent code is input on DACs. Specified in each of SD and HD groups.
note 4 ) DAC 5 channels “ ON “ ( SD : on-chip color bar
note 5 ) values are after initialization of internal filter by either INT_N or by register setting, and before the Power-down.
(AVDD = 2.66 ~ 3.45V, IVDD = DVDD = 1.65 ~ 2.0V, IIC_VDD = DVDD ~ 3.45V, Ta= -20~ 85°C )
