FEATURES (• new feature not found on MSM7662)
• High speed of burst locking has been realized.
• 2-dimensional Y/C separation using adaptive comb filter (this filter is bypassed for S-video
• Built-in vertical chrominance filter (straight output without using the filter is possible)
• Recognition of data in the VBI period (closed caption, CGMS, WSS, macrovision AGC and
• Hi-Z mode for output pins
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)

signal input)
NTSC format: 3 lines or 2 lines, PAL format: 2 lines (adaptive transition method)
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)
12.272727 MHz (12.272727/24.545454 MHz) : NTSC Square pixel
14.31818 MHz (14.31818/28.63636 MHz)
14.75 MHz (14.75/29.5 MHz)
pseudo pulse) and function of reading from I
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
Multiplex signal recognition (closed caption)
During vertical blanking interval, data is output as 8-bit data.
