Philips Semiconductors
Enhanced Video Input Processor (EVIP)
Product specification
SAA7111A
1 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 × fH = 13.5 MHz for 625 line sources
– 858 × fH = 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, 6, and 5) (16-bit) with dither
– RGB (8, 8, and 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 I2C-bus for INTERCAST applications
• Power-on control
• Two via I2C-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)
• I2C-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.
2 APPLICATIONS
• Desktop/Notebook (PCMCIA) video
• Multimedia
• Digital television
• Image processing
• Video phone
• Intercast.
