GENERAL DESCRIPTION
The TDA3565 PAL decoder contains all the functions required for PAL signal decoding and colour matrixing and is contained within an 18-pin package. The oscillator, a.c.c. detector and burst phase detector each have single-pin outputs and the coupling capacitor for the luminance input at pin 8 doubles as a storage capacitor for the black level clamping circuit. Black level clamping of the three colour channels is performed using feedback proportional to the red channel black level. This feedback (variable with the brightness control) controls the input level of the luminance amplifier and therefore the clamping levels of all three colour signal outputs.

Notes to the characteristics
1. At nominal contrast and nominal brightness.
2. Signal with negative-going sync pulse, amplitude includes sync pulse amplitude.
3. The signal indicated is for a colour bar with 75% saturation, so the chroma burst ratio of 2,2 : 1.
4. Nominal contrast is defined as (maximum contrast−3dB) and nominal saturation is (maximum saturation−12 dB).
5. Cross coupling is measured under the following condition; input signals nominal and contrast/saturation such that nominal output signals are obtained. The signals at the output at which no signal should be available must be compared with the nominal signal at that output.
6. The signal-to-noise ratio is specified as peak-to-peak signal with respect to r.m.s. noise.
7. These signal amplitudes are determined by the a.c.c. circuit of the reference part.
8. When this level is exceeded the amplitude of the output signal is reduced via a discharge of the capacitor at pin 6 (contrast control). The discharge current is 5,5 mA.

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”
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 be necessary immediately after soldering to keep the temperature within the permissible limit.
(order code 9398 652 90011).
). If the printed-circuit board has been pre-heated, forced cooling may
stg max
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.
