AN-796 APPLICATION NOTE
Using the ADV202 in a Multichip Application
by Christine Bako
INTRODUCTION This application note provides instructions on how to interface two ADV202s when used in HDTV, 1080i mode. SMPTE274M 1080i video at 60 fields/sec translates to a total data rate of 1.485 Gbps. This translates to an input data rate of active video of approximately 124 Mbytes/sec for 10-bit data. The ADV202 limits data input rates to 65 MSPS in irreversible mode or 32 MSPS in reversible mode using the VDATA interface. This requires at least two ADV202s to manage the data input rates for 1080i. Using two ADV202s in HDTV mode, the ADV202 expects Y and CbCr to be on separate buses: AD……
