The TDA4565 from N-A is a monolithic integrated circuit specifically designed for colour transient improvement (CTI) and as a luminance delay line in colour television receivers. It utilizes a gyrator technique to achieve its functionality.
Key features include colour transient improvement for (R-Y) and (B-Y) colour difference signals, providing high transients. It also incorporates a luminance signal path that replaces the conventional Y-delay coil with an integrated Y-delay line. The delay time is switchable, ranging from 730 ns to 1000 ns in 90 ns steps, with an additional 50 ns fine adjustment. Two Y output signals are provided, with one having a 180 ns less delay.
The device operates within a supply voltage range of 10.8 V to 13.2 V, typically 12 V, and draws a supply current of 35 mA to 50 mA. The Y-signal delay can be adjusted based on external resistor R14-18 and voltage V15-18, with typical values ranging from 730 ns to 1000 ns. The Y-signal attenuation is typically 6.5 dB at 0.5 MHz, while the (R-Y) and (B-Y) signal attenuation is between -10 dB and +1 dB. The output transient time is typically between 100 ns and 200 ns.
The TDA4565 is available in an 18-lead DIL plastic package (SOT102). It operates within an ambient temperature range of 0 °C to 70 °C and has a total power dissipation of 1.1 W at 70 °C ambient temperature. The junction to ambient thermal resistance is 70 K/W.
