Multimedia video data acquisition circuit
SAA5284
Notes
1. ESD protection of this pin falls below the Philips General Quality Specification (GQS). Therefore it is recommended
that a diode is connected from pin RDY to VDDD.
2. The I2C-bus interface pins SDA and SCL may pull the data and clock lines below 3 V while the digital power supply
VDDD is in the range 0.4 to 0.8 V.
