GENERAL DESCRIPTION
The TDA2595 is a monolithic integrated circuit intended for use in colour television receivers.
Features
Positive video input; capacitively coupled (source impedance
<
200
)
Adaptive sync separator; slicing level at 50% of sync amplitude
Internal vertical pulse separator with double slope integrator
Output stage for vertical sync pulse or composite sync depending on the load; both are switched off at muting
1
phase control between horizontal sync and oscillator
Coincidence detector
3
for automatic time-constant switching; overruled by the VCR switch
Time-constant switch between two external time-constants or loop-gain; both controlled by the coincidence detector
3
1
gating pulse controlled by coincidence detector
3
Mute circuit depending on TV transmitter identification
2
phase control between line flyback and oscillator; the slicing levels for
2
control and horizontal blanking can be set
separately
Burst keying and horizontal blanking pulse generation, in combination with clamping of the vertical blanking pulse
(three-level sandcastle)
Horizontal drive output with constant duty cycle inhibited by the protection circuit or the supply voltage sensor
Detector for too low supply voltage
Protection circuit for switching off the horizontal drive output continuously if the input voltage is below 4 V or higher
than 8 V
Line flyback control causing the horizontal blanking level at the sandcastle output continuously in case of a missing
flyback pulse
Spot-suppressor controlled by the line flyback control

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 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 (T
stg 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.
