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.
