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.
