Description
The integrated delay line circuit U3665M is suitable for all chroma decoders with baseband color-difference outputs. It is suitable for PAL-, SECAM- and NTSC-signals as well. The U3665M contains two separate delay lines for processing (R–Y)-output and (B–Y)-output separately. The delay is performed by internally switched capacitors. On-chip postfiltering avoids the need for external filter components. In the case of the U3665M, the postfilter is tuned to Bessel-characteristic.
Features
● One line delay time, addition of delayed and non-delayed output signals
● Adjustment-free application, VCO without external components
● Handles negative or positive color-difference input signals
● Clamping of AC-coupled input signals [±(R–Y) and ±(B–Y)]
● Line-locked by the sandcastle pulse
● No crosstalk between SECAM color carriers (diaphoty)
● Comb-filtering functions for NTSC colordifference signals
● Correction of phase errors in the PAL systemApplication
In TV sets, the integrated baseband delay line circuit is suitable for decoders with color-difference signal outputs
