General Description SDA 9488X ’PIP IV Basic’ and SDA 9588X ’OCTOPUS’ belong to a new generation of costeffective PiP processors that combine high-quality digital PIP signal processing, digital multistandard color decoding and AD/DA conversion on a single chip. Both devices are equipped with CVBS and Y/C input interfaces. In addition the SDA 9588X is also able to process YUV input signals for displaying high-quality video signals e.g. coming from a DVD source. Features • Single chip solution: – AD-conversion for CVBS or Y/C or YUV1), multistandard color decoding, PLL for synchronization of inset channel, decimation filtering, embedded memory, RGBmatrix, DA-conversion, RGB/YUV switch, data-slicer and clock generation integrated on chip • Analog inputs: – 3x CVBS or 1x CVBS and 1x Y/C or 1xYUV (SDA 9588X) alternatively – Clamping of each input – All ADCs with 8 bit amplitude resolution – Automatic Gain Control (AGC) for Y and CVBS • Inset Synchronization: – Multiple time constants for reliable synchronization – Automatic recognition of 625 lines / 525 lines standard • Color Decoder: – PAL-B/G, PAL-M, PAL-N(Argentina), PAL60, NTSC-M, NTSC4.4 and SECAM – Adjustable color saturation – Hue control for NTSC – Automatic Chroma Control (-24 dB ... +6 dB) – Automatic recognition of chroma standards: different search strategies selectable – Single crystal for all standards – IF-characteristic compensation filter • Decimation: – PIP sizes between 1/81 and 1/9 adjustable with steps of 2 lines and 4 pixel – Resolution up to 216 luminance and 2x54 chrominance pixels per inset line – Horizontal and vertical filtering dependent on picture size • Display Features: – 7 bit per pixel stored in memory – Field and joint-line free frame mode display – Display on VGA and SVGA screen (fH limited to 40kHz) – 8 different read frequencies for 16:9 compatibility – Line doubling mode for progressive scan applications – Freeze picture – Coarse positioning at 4 corners of the parent picture – Fine positioning at steps of 4 pixels and 2 lines • Output signal processing: – 7 Bit DAC – RGB or YUV switch: insertion of an external source without PIP processing – Digital interpolation for anti-imaging – Adjustable transient improvement for luma (peaking) – Contrast, Brightness and Pedestal Level adjustable – Analog outputs: Y, +(B-Y), +(R-Y), or Y, -(B-Y), -(R-Y) or RGB – Three RGB matrices available: NTSC(Japan), NTSC(USA) or EBU – 64 different background colors and 4096 different frame colors – Plain or 3D frame with variable width and height • Data Slicing: – Slicing of closed-caption (CC) or wide-screen-signaling (WSS) data – Violence blocking capability (V-chip) – Several filter for XDS data extraction • I2C-Bus control (400 kHz) • High stability clock generation • PDSO 28-1 package (SMD) • Full SDA 9489X and SDA 9589X upward compatibility • SDA 9388X / SDA 9389X pinout compatibility • 3.3V supply voltage (5V input capable)
