AK8854VQ
Multi-Format Digital Video Decoder
Overview
The AK8854VQ is a single-chip digital video decoder for composite, s-video, component YPbPr and
RGB video signals. In case of RGB, AK8854VQ support Sync on Green,CSYNC and H/VSYNC as
sync signal. Its output data is in YCbCr format, compliant with ITU-R BT.601. Its pixel clock, with a
generated clock rate of 27 MHz, synchronizes with the input signal. Its output interface is ITU-R BT.656
compliant. Microprocessor access is via a I²C interface. The operating temperature range is −40°C to
85°C. The package is 64-terminal LQFP.
