(1 PC) SAA7186HB PHILIPS Digital video scaler 100 PIN QFP

1 FEATURES • Scaling of video picture windows down to randomly sized windows • Processes maximum 1023 pixels per line and 1023 lines per field • Two-dimensional data processing for improved signal quality of scaled video data and for compression of video data • 16-bit YUV input data buffer • Interlace/non-interlace video data processing and field control • Line memories in Y path and UV path to store two lines, each with 2 × 768 × 8 bit capacity • Vertical sync processing by scale control • Non-scaled mode to get full picture or to gate videotext lines • UV input and output data binary/two’s complement • Switchable RGB matrix and anti-gamma ROMs • 16-word FIFO register for 32-bit output data • Output formats: 5-bit and 8-bit RGB, 8-bit YUV or 8-bit monochrome

2 GENERAL DESCRIPTION The CMOS circuit SAA7186 scales and filters digital video data to randomly sized picture windows. YUV input data in 4:2:2 format are required (SAA7191B source)
