FEATURES (• new feature not found on MSM7662)

° 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)

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

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)

• High speed of burst locking has been realized.

• 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 (adaptive transition method)

• Built-in vertical chrominance filter (straight output without using the filter is possible)

° 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).

° Compatible pixel frequencies (normal/twice the pixel frequency)

13.5 MHz (13.5/27 MHz)

: NTSC/PAL ITU-RBT.601

12.272727 MHz (12.272727/24.545454 MHz) : NTSC Square pixel

14.31818 MHz (14.31818/28.63636 MHz)

: NTSC 4fsc

14.75 MHz (14.75/29.5 MHz)

: PAL Square Pixel

• Recognition of data in the VBI period (closed caption, CGMS, WSS, macrovision AGC and

pseudo pulse) and function of reading from I2C-bus (only for ITU-RBT.601 mode).

° Built-in AGC/ACC circuits, compatible with a wide range of input levels

Input level range: –8 dB to +3.5 dB (0.4 V to 1.5 V)

Switchable between AGC/MGC (fixed gain) and ACC/MCC (fixed gain)

° Decimation filter built into input stage, allows easy configuration of filter prior to A/D

converter (when input at twice the pixel frequency)

° Automatic NTSC/PAL recognition (only for ITU-RBT.601)

° Sleep mode

• Hi-Z mode for output pins

° Multiplex signal recognition (closed caption)

During vertical blanking interval, data is output as 8-bit data.

° I2C-bus interface

° 3.3 V single power supply (I/O 5 V tolerance)

° Package:

100-pin plastic TQFP (TQFP100-P-1414-0.50-K) (Product name: MSM7664TB)
