1 1.1 FEATURES Video decoder
SAA7108E; SAA7109E
· Six analog inputs, internal analog source selectors, e.g. 6 × CVBS or (2 × Y/C and 2 × CVBS) or (1 × Y/C and 4 × CVBS) · Two analog preprocessing channels in differential CMOS style for best S/N-performance · Fully programmable static gain or Automatic Gain Control (AGC) for the selected CVBS or Y/C channel · Switchable white peak control · Two built-in analog anti-aliasing filters · Two 9-bit video CMOS Analog-To-Digital Converters (ADCs), digitized CVBS or Y/C signals are available on the IPD (Image Port Data) port under I2C-bus control · On-chip clock generator · Line-locked system clock frequencies · Digital PLL for horizontal sync processing and clock generation, horizontal and vertical sync detection · Requires only one crystal (either 24.576 MHz or 32.11 MHz) for all standards · Automatic detection of 50 and 60 Hz field frequency, and automatic switching between PAL and NTSC standards · Luminance and chrominance signal processing for PAL BGHI, PAL N, combination PAL N, PAL M, NTSC M, NTSC-Japan, NTSC N, NTSC 4.43 and SECAM · User programmable luminance peaking or aperture correction · Cross-colour reduction for NTSC by chrominance comb filtering · PAL delay line for correcting PAL phase errors · Brightness Contrast Saturation (BCS) and hue control on-chip · Two multi functional real-time output pins controlled by I2C-bus · Multi-standard VBI data slicer decoding World Standard Teletext (WST), North-American Broadcast Text System (NABTS), Closed Caption (CC), Wide Screen Signalling (WSS), Video Programming System (VPS), Vertical Interval Time Code (VITC) variants (EBU/SMPTE) etc. · Standard ITU 656 Y-CB-CR 4 : 2 : 2 format (8-bit) on IPD output bus · Enhanced ITU 656 output format on IPD output bus containing: active video raw CVBS data for INTERCAST applications (27 MHz data rate) decoded VBI data · Detection of copy protected input signals according to the macrovision standard. Can be used to prevent unauthorized recording of pay-TV or video tape signals. 1.2 Video scaler
· Both up and downscaling · Conversion to square pixel format · NTSC to 288 lines (video phone) · Phase accuracy better than 1/64 pixel or line, horizontally or vertically · Independent scaling definitions for odd and even fields · Anti-alias filter for horizontal scaling · Provides output as scaled active video raw CVBS data for INTERCAST, WAVE-PHORE, POPCON applications or general VBI data decoding (27 MHz or sample rate converted) · Local video output for Y-CB-CR 4 : 2 : 2 format (VMI, VIP, ZV). 1.3 Video encoder
· Digital PAL/NTSC encoder with integrated high quality scaler and anti-flicker filter for TV output from a PC · 27 MHz crystal-stable subcarrier generation · Maximum graphics pixel clock 45 MHz at double edged clocking, synthesized on-chip or from external source · Up to 800 × 600 graphics data at 60 Hz or 50 Hz with programmable underscan range · Three Digital-to-Analog Converters (DACs) at 27 MHz sample rate for CVBS (BLUE, CB), VBS (GREEN, CVBS) and C (RED, CR) (signals in parenthesis are optional); all at 10-bit resolution
