Semiconductor NTSC/PAL Digital Video Decoder
GENERAL DESCRIPTION
MSM7664 device that decodes NTSC analog video signals into YCbCr digital data based ITU-RBT.601. device built-in channels converters accept composite video video signals input video signals. Composite video signals converted YCbCr digital data 2-dimensional separation circuit with adaptive filter. Analog video signals sampled clock pixel frequency twice pixel frequency. decimation filter built-in sampling twice pixel frequency. Input signals synchronized internally high-speed locking color burst possible. Because FIFO buffer built into output format circuit, jitter-free output obtained even non-standard signals. MSM7664 improved version MSM7662, particularly superior picture quality stabilization synchronization decoder well stabilization synchronization decoder under weak electric fields. Further, although part registers have been added, electrical characteristics both products almost identical their compatibility makes possible MSM7664 instead MSM7662.
APPLICATION EXAMPLES
Since synchronization input signals high-speed locking color burst possible, device optimized applications used switching multiple cameras. also used various image processing applications because jitter-free output data through built-in FIFO buffer. Even mode, separation characteristics equivalent NTSC mode been achieved thereby making this ideally suitable mode applications. 8-bit (YCbCr), 16-bit (8-bit 8-bit (CbCr)), 24-bit (RGB) output interfaces selected output mode that various devices such monitoring system, digital video memory, digital video processing unit video communication unit selected receiving side.

Select either 16-bit [YCbCr] output output interface. Number field memories utilized 16-bit [YCbCr]: field memories. RGB: field memories. Video input four composite inputs S-Video inputs. Connect unused video input pins AGND. composite signal input, input side (video amp, converter, etc.) will operation state. input limited composite signal, connect (5:6), VRT2, VRB2, AMPOUT2, ADIN2, CLPOUT2 pins AGND. Externally attached components such capacitors removed. MODE[3:0] pins prescribed setting. FM-1 mode setting, externally generate supply control signals field memory. FM-2 mode setting, memory control signals from M[7:4] supplied field memory. FM-2 mode setting, output timing HSYNC_L, VSYNC_L, ODD, VVALID, HVALID becomes memory read timing. Data output from memory aligned with various sync signal timings. (See page page Supply power analog, A/D, digital circuits circuit board should separated power source wherever possible. Power lines analog circuits must wide impedance. 73/76

NOTES
decoder encoder have multiple registers improving stabilizing their characteristics, these registers have function default values standard signals. Video signals different from standard signals input depending user applications. this case, recommended each register different values from default values stabilize decode operations under user's requirements. Please contact these register settings. Stable decode operations cannot always guaranteed depending input video signals. Each register vary setting values over wide range stable operations cannot guaranteed setting values.
