Product specification
9-bit video input processor
SAA7113H
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 in differential
CMOS style for best S/N-performance
• Fully programmable static gain or automatic gain control
for the selected CVBS or Y/C channel
• Standard ITU 656 YUV 4 : 2 : 2 format (8-bit) on VPO
output bus
• Switchable white peak control
• Enhanced ITU 656 output format on VPO output bus
• Two built-in analog anti-aliasing filters
containing:
• Two 9-bit video CMOS Analog-to-Digital Converters
(ADCs), digitized CVBS or Y/C-signals are available on
the VPO-port via I2C-bus control
– active video
– raw CVBS data for INTERCAST applications
(27 MHz data rate)
• On-chip clock generator
– decoded VBI data
• Line-locked system clock frequencies
• Boundary scan test circuit complies with the “IEEE Std.
1149.b1 - 1994” (ID-Code = 1 7113 02B)
• I2C-bus controlled (full read-back ability by an external
controller, bit rate up to 400 kbits/s)
• Digital PLL for horizontal sync processing and clock
generation, horizontal and vertical sync detection
• Requires only one crystal (24.576 MHz) for all standards
• Automatic detection of 50 and 60 Hz field frequency,
and automatic switching between PAL and NTSC
standards
• Low power (<0.5 W), low voltage (3.3 V), small package
(QFP44)
• Power saving mode by chip enable input
• 5 V tolerant digital I/O ports
• Luminance and chrominance signal processing for
PAL BGHI, PAL N, combination PAL N, PAL M,
NTSC M, NTSC N, NTSC 4.43, NTSC-Japan and
SECAM
• 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.
• User programmable luminance peaking or aperture
correction
