W9952QP is designed for digital video applications,such as VCDs (Video CDs), STBs (Set-Top Box) and video games.

Figure 2 shows a typical configuration of W9952QP application.

The  W9952QP  digital  video  encoder  converts YCbCr    (4:2:2)  8-bit  data  into  analog  composite video and Y/C video signals. W9952QP accepts ITU-601/656 or square pixel input formats, and the output video is formatted to be compatible with 525-line (M) NTSC/ PAL or 625-line (B,D,G,H,I,M,Nc) PAL TV System.

The  W9952QP  operates  in  both  master  or  slave modes. At slave mode,the W9952QP auto detects the  input  video  format  from  the  HSYNCN  and VSYNCN  pins  and  generates  the  corresponding video  signals.  At  master  mode,  It  generates  the required  video  timing  internally  according  to  the configuration.

The  W9952QP  has  two  DAC  outputs  which  can output either two composite video signals or one Y/C S-video  signal.  The  W9952QP  doesn't  output composite video and S-video simultaneously.The W9952QP can operate at power-down mode by selecting the SLEEP pin.

The W9952QP  is  designed  to  connect  to MPEG1 and MPEG2  video decoders without glue  logic. All video  processing  is  done  digitally  and  requires  no external adjustment and no software programming is required.
