Product speciﬁcation

9-bit video input processor

SAF7113H

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

• 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 VPO-port via 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 (24.576 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 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

• Brightness Contrast Saturation (BCS) and hue control

on-chip

• Real-time status information output (RTCO)

• 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, Wide Screen

Signalling (WSS), Video Programming System (VPS),

Vertical Interval Time Code (VITC) variants

(EBU/SMPTE) etc.

• Standard ITU 656 YUV4:2:2 format (8-bit) on VPO

output bus

• Enhanced ITU 656 output format on VPO output bus

containing:

– active video

– raw CVBS data for INTERCAST applications

(27 MHz data rate)

– decoded VBI data

• 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)

• Low power (<0.5 W), low voltage (3.3 V), small package

(QFP44)

• Power saving mode by chip enable input

• 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.

APPLICATIONS

• Notebook (low power consumption)

• PCMCIA card application

• AGP based graphics cards

• Image processing

• Video phone applications

• Intercast and PC teletext applications

• Security applications.
