NTSC/PAL Digital Video Decoder

GENERAL DESCRIPTION

The MSM7662 is an LSI device that decodes NTSC or PAL analog video signals into YCbCr and

RGB digital data based on ITU-RBT.601.

The device has built-in two channels of A/D converters and can accept composite video and S

video signals for the input video signals. Composite video signals are converted to YCbCr and

RGB digital data via the 2-dimensional Y/C separation circuit with an adaptive filter.

Analog video signals can be sampled by a clock at the pixel frequency or at twice the pixel

frequency. A decimation filter is built-in for sampling at twice the pixel frequency.

Input signals are synchronized internally and high-speed locking for color burst is possible.

Because a FIFO buffer is built into the output format circuit, jitter-free output can be obtained

even for non-standard signals.

APPLICATION EXAMPLES

Sincethesynchronizationofinputsignalsandhigh-speedlockingforcolorburstarepossible,the

device is optimized for applications used by switching multiple cameras.

It is also used for various image processing applications because of jitter-free output data

through a built-in FIFO buffer.

8-bit (YCbCr), 16-bit (8-bit (Y) + 8-bit (CbCr)), and 24-bit (RGB) output interfaces can be selected

as an output mode so that various devices such as monitoring system, digital video memory,

digital TV, video processing unit and video communication unit can be selected on the receiving

side.

FEATURES (• new feature not found on MSM7661B)

• Input analog signal

NTSC/PAL composite video signal or S-video signal

• Maximum 5 composite or 2 S-video + 2 composite analog inputs can be connected (switchable

by external pins or internal registers)

• Built-in clamp circuits and video amps

• Built-in 8-bit A/D converters (2 channels)

• 4 selectable output interfaces

ITU-RBT.656 (conditional)

8-bit (YCbCr)

16-bit (YCbCr) : 8-bit (Y) + 8-bit (CbCr) YCbCr = 4 : 2 : 2/YCbCr = 4 : 1 : 1 (limit)

24-bit RGB : 8-bit (R) + 8-bit (G) + 8-bit (B)

: 8-bit (YCbCr) YCbCr = 4 : 2 : 2/YCbCr = 4 : 1 : 1 (limit)

2-dimensional Y/C separation using adaptive comb filter (this filter is bypassed for S-video

signal input)

NTSC format: 3 lines or 2 lines, PAL format: 2 lines (3 virtual lines)

• Selectable data I/O signal synchronization

4 synchronization modes, internal FIFO modes (FIFO-1, FIFO-2) and external field memory

modes (FM-1, FM-2), are selectable (FIFO-1 is normally selected).
