Digital Video Encoder (ECO-DENC)
Preliminary specification
SAA7124; SAA7125
FEATURES
• Monolithic CMOS 5 V device
• Digital PAL/NTSC encoder
• System pixel frequency 13.5 MHz
• Accepts MPEG decoded data on 8-bit wide input port.
Input data format Cb, Y, Cr etc. “(CCIR 656)”
• Four DACs for CVBS (10-bit resolution), RGB (9-bit
resolution) operating at 27 MHz; RGB sync on CVBS
• Optionally 2 times CVBS and Y, C (all 10-bit resolution)
available simultaneously
• Closed captioning encoding
• On-chip YUV to RGB dematrix optionally to be
by-passed for Cr, Y, Cb output on RGB DACs
• Fast I2C-bus control port (400 kHz)
• Encoder can be master or slave
• Programmable horizontal and vertical input
synchronization phase, via input pins or auxiliary codes
at MP data port
• Programmable horizontal sync output phase
• Internal 100/75 Colour Bar Generator (CBG)
• Macrovision Pay-per-View copy protection system as
option, also partly used for RGB output.
This applies to SAA7124 only. The device is protected
by USA patent numbers 4631603, 4577216 and
4819098 and other intellectual property rights. Use of
the Macrovision anti-copy process in the device is
licensed for non-commercial home use only.
Reverse engineering or disassembly is prohibited.
Please contact your nearest Philips Semiconductor
sales office for more information
• Controlled rise and fall times of output syncs and
blanking
• Down-mode of DACs
• LQFP64 (V1 devices only), QFP80 or PLCC84
package.
GENERAL DESCRIPTION
The SAA7124; SAA7125 encodes digital YUV video data
to an NTSC or PAL CVBS plus RGB or alternatively to
S-Video and CVBS output.
Optionally, the YUV to RGB dematrix can be by-passed
providing the digital-to-analog converted Cb, Y, Cr signals
instead of RGB.
The circuit accepts CCIR compatible YUV data with
720 active pixels per line in 4 : 2 : 2 multiplexed formats,
for example MPEG decoded data.
It includes a sync/clock generator and on-chip
Digital-to-Analog Converters (DACs).
