芯德斯解密团队在M65667FP解密项目中取得的重大成果,现可为广大需求客户提供优质可靠、价格合理的IC解密及同类型解密方案,以下我们针对此芯片的主要功能特性做简要介绍仅供各类芯片解密工程师与客户参考:
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.
