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.

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.
