5. Electrical Characteristics
■ Absolute Maximum Ratings (* Power supply voltages are values where each ground pin(DVSS=AVSS) is at 0V)
■ Recommended Operating Conditions
■ Analog Characteristics and Power Dissipation
Rev-E-00
* All power supply ground pins (DVSS, AVSS) should be at the same potential.
Note 1. DAC:148MHz Operation
Note 2. 2MHz Sin-wave input. (Noise Band-Width 0 – 30MHz)
Note 3. Output Bandwidth 30MHz: at 148MHz Operation DAC1 (Load Resistor 300ohm) Channel Only External Load
Note 4. Variation when a 700 mV equivalent code is input on DACs.
Note 5. DAC 3ch ON fs=74MHz / Component mode (Y: 30MHz Sin wave, CbCr: 15MHz Sin wave)
Note 6: Clock-rate and Input data is
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
