FUNCTIONAL DESCRIPTION
TDA4560
The IC consists of two colour difference channels (B-Y) and (R-Y) and a luminance signal path (Y) as shown in Fig.1. Colour difference channels The (B-Y) and (R-Y) colour difference channels consist of a buffer amplifier at the input, a switching stage and an output amplifier. The switching stages, which are controlled by transient detecting stages (differentiators), switch to a value that has been stored at the beginning of the transients. The differentiating stages get their signal direct from the colour difference detecting signal (pins 1 and 2). Two parallel storage stages are incorporated in which the colour difference signals are stored during the transient time of the signal. After a time of about 600 ns they are switched immediately (transient time of 150 ns) to the outputs. The colour difference channels are not attenuated. Y-signal path The Y-signal input (pin 17) is capacitively coupled to an input clamping circuit. Gyrator delay cells provide a maximum delay of 1035 ns including an additional delay of 45 ns via the fine adjustment switch (S1) at pin 13. Three delay cells are switched with two interstage switches dependent on the voltage at pin 15. Thus three switchable delay times of 90 ns, 180 ns or 270 ns less than the maximum delay time are available. A tuning compensation circuit ensures accuracy of delay time despite process tolerances. The Y-signal path has a 7 dB attenuation as a normal Y-delay coil and can replace this completely. The output is fed to pin 12 via a buffer amplifier. An additional output stage provides a signal of 90 ns less delay at pin 11 for the option of velocity modulation. RATINGS Limiting values in accordance with the Absolute Maximum System (IEC) Supply voltage (pin 10) Voltage ranges to pin 18 (ground) at pins 1,2,12,15 at pin 11 at pin 17 Voltage ranges at pin 7 to pin 6 at pin 8 to pin 9 Currents at pins 6,9 at I7, I8, I11, I12 Total power dissipation Storage temperature range Operating ambient temperature range Note 1.

SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "IC Package Databook" (order code 9398 652 90011). Soldering by dipping or by wave The maximum permissible temperature of the solder is 260 °C; solder at this temperature must not be in contact DEFINITIONS Data sheet status Objective specification Preliminary specification Product specification Limiting values

with the joint for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds. The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (Tstg max). If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. Repairing soldered joints Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 °C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 °C, contact may be up to 5 seconds.
