Philips Semiconductors
Video Enhancement and
Digital-to-Analog processor (VEDA2)
Product specification
SAA7165
FEATURES
• CMOS circuit to enhance video data and to convert
luminance and colour-difference signals from
digital-to-analog
• Digital Colour Transient Improvement block (DCTI) to
increase the sharpness of colour transitions.
The improved pin-compatible SAA7165 can supersede
the SAA9065
• 16-bit parallel input for 4 : 1 : 1 and 4 : 2 : 2 YUV data
• Data clock input LLC (Line-Locked Clock) for a data rate
up to 36 MHz
• 8-bit luminance and 8-bit multiplexed colour-difference
formats (7-bit formats optional)
• MC input to support various clock and pixel rates
• Formatting YUV input data; 4 : 2 : 2 format,
4 : 1 : 1 format and filter characteristics selectable
• HREF input to determine the active line (number of
pixels)
• Controllable peaking of luminance signal
• Coring stage with controllable threshold to eliminate
noise in luminance signal
• Interpolation filter suitable for both formats to increase
the data rate in chrominance path
• Polarity of colour-difference signals selectable
• All functions controlled via I2C-bus
• Separate digital-to-analog converters (9-bit resolution
for Y; 8-bit for colour-difference signals)
• 1 V (p-p)/75 Ω outputs realized by two resistors
• No external adjustments.
