GENERAL DESCRIPTION
The TDA4560 is a monolithic integrated circuit for colour transient improvement (CTI) and luminance delay line in gyrator
technique in colour television receivers.
Features
• Colour transient improvement for colour difference signals (R-Y) and (B-Y) with transient detecting-, storage- and
switching stages resulting in high transients of colour difference output signals
• A luminance signal path (Y) which substitutes the conventional Y-delay coil with an integrated Y-delay line
• Switchable delay time from 720 ns to 1035 ns in steps of 45 ns
• Output for the option of velocity modulation

FUNCTIONAL DESCRIPTION
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.

time of successive solder waves must not exceed
5 seconds.
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.
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.
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).
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.
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
