Description
The M65667FP is a NTSC PIP (Picture in Picture) signal processing LSI, whose sub and main-picture inputs are
composite and Y/C separated signals, respectively. The built-in field memory (96 Kbit RAM), V-chip data slicer and
analog circuitries lead the PIP system low cost and small size.
Features
• Built-in 96 Kbit field memory (sub-picture data storage)
• Internal V-chip data slicer (for sub-picture)
• Vertical filter for sub-picture (Y signal)
• Single sub-picture (selectable picture size: 1/9, 1/16)
• Sub-picture processing specification (1/9 size / 1/16 size)
Quantization bits Y, B-Y, R-Y: 6 bits
Horizontal sampling 171 pixels (Y), 28.5 pixels (B-Y, R-Y)
Vertical lines
69/52 lines
• Frame (sub-picture) on/off
• Built-in analog circuits
Two 8-bit A/D converters (main and sub-picture signals)
Two 8-bit D/A converters (Y and C sub-picture signals)
Sync-tip-clamp, VCXO, Analog switch, etc.
• I²C BUS control (parallel/serial control)
PIP on/off, Sub-picture size (1/9 or 1/16), Frame on/off (programmable luma level), PIP position (4 corners fixed
position), Picture freeze, Y delay adjustment, Chroma level, Tint, Black level, Contrast, etc.
