SDA9588X

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
