Description

The Enhanced Video Input Processor (EVIP) is a combination of a two-channel analog preprocessing circuit including source selectionanti-aliasing filter and ADCan automatic clamp and gain controla Clock Generation Circuit (CGC)a digital multi-standard decoder (PAL BGHIPAL MPAL NNTSC M NTSC-Japan NTSC N and SECAM)a brightness/contrast/saturation control circuita colour space matrix (see Fig.1) and a 27 MHz VBI-data bypass.

Features

• Four analog inputs, internal analog source selectors, e.g. 4 ´ CVBS or 2 ´ Y/C or (1 ´ Y/C and 2 ´ CVBS)
• Two analog preprocessing channels
• Fully programmable static gain for the main channels or automatic gain control for the selected CVBS or Y/C channel
• Switchable white peak control
• Two built-in analog anti-aliasing filters
• Two 8-bit video CMOS analog-to-digital converters
• On-chip clock generator
• Line-locked system clock frequencies
• Digital PLL for horizontal-sync processing and clock generation
• Requires only one crystal (24.576 MHz) for all standards
• Horizontal and vertical sync detection
• 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, PAL M, NTSC M, NTSC N, NTSC 4.43, NTSC-Japan 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
• Real time status information output (RTCO)
• Brightness Contrast Saturation (BCS) control on-chip
• The YUV (CCIR-601) bus supports a data rate of:
  – 864 ´ f_H= 13.5 MHz for 625 line sources
  – 858 ´ f_H = 13.5 MHz for 525 line sources.
• Data output streams for 16, 12 or 8-bit width with the following formats:
  – YUV 4 :1 :1 (12-bit)
  – YUV 4 :2 :2 (16-bit)
  – YUV 4 :2 :2 (CCIR-656) (8-bit)
  – RGB (5, 6and 5) (16-bit) with dither
  – RGB (8, 8and 8) (24-bit) with special application.
• Odd/even field identification by a non interlace CVBS input signal
• Fix level for RGB output format during horizontal blanking
• 720 active samples per line on the YUV bus
• One user programmable general purpose switch on an output pin
• Built-in line-21 text slicer
• A 27 MHz Vertical Blanking Interval (VBI) data bypass programmable by I₂PC-bus for INTERCAST applications
• Power-on control
• Two via I₂PC-bus switchable outputs for the digitized CVBS or Y/C input signals AD1 (7 to 0) and AD2 (7 to 0)
• Chip enable function (reset for the clock generator and power save mode up from chip version 3)
• Compatible with memory-based features (line-locked clock)
• Boundary scan test circuit complies with the ‘IEEE Std. 1149.1- 1990’ (ID-Code = 0 F111 02 B)
• I₂PC-bus controlled (full read-back ability by an external controller)
• Low power (<0.5 W), low voltage (3.3 V), small package (LQFP64)
• 5 V tolerant digital I/O ports.

Applications

• Desktop/Notebook (PCMCIA) video
• Multimedia
• Digital television
• Image processing
• Video phone
• Intercast.
