General Description The Picture-in-Picture Processor SDA 9288X A141 generates a picture of reduced size of a video signal (inset channel) for the purpose of combining it with another video signal (parent channel). The easy implementation of the IC in an existing system needs only a few additional external components. Features • Single chip solution Clamping, AD conversion, filtering, field memory, RGB matrix, DA-conversion and clock generation integrated on one chip • 2 picture sizes 1/9 or 1/16 of normal size 212 luminance and 53 chrominance pixels per inset line for picture size 1/9 6-bit amplitude resolution for each incoming signal component Field and frame mode display Horizontal and vertical filtering Special antialias filtering for the luminance signal • 16:9 compatibility Operation in 4:3 and 16:9 sets 4:3 inset signals on 16:9 displays or v.v. with picture size 1/9 and 1/16, respectively • Analog inputs Y, + (B-Y), + (R-Y) or Y, -(B-Y), -(R-Y) • Analog outputs Y, + (B-Y), + (R-Y) or Y, – (B-Y), – (R-Y) or RGB 3 RGB matrices: EBU, NTSC (Japan), NTSC (USA) • Free programmable position of inset picture Steps of 1 pixel and 1 line All PIP and POP positions are possible • Programmable framing 4096 frame colors Variable frame width • High resolution display 13.5 MHz/27 MHz display clock frequency • Freeze picture • I2C Bus control • Threefold PIP/POP facility Three different I2C-addresses (pin-programmable) Tri-State outputs • Numerical PLL circuit for high stability clock generation • No necessity of PAL/SECAM delay lines (using suitable color decoders i.e. TDA 8310) • Multistandard applications 625 lines/525 lines standard (inset and parent channel) Scan conversion systems as flickerfree display systems (parent channel) HDTV (parent channel) • P-DSO-32-2 package/350 mil (SMD) • 5 V supply voltage
