FUNCTIONAL DESCRIPTION

DIVIDER STAGES The divider stages provide−(R-Y) and−(B-Y) reference signals with the correct 90 degrees relation for the demodulators. PHASE COMPARATOR The phase comparator compares the −(R-Y) reference signal with the burst pulse and controls the frequency and phase

of the reference oscillator. IDENTIFICATION DEMODULATOR The identification demodulator delivers a positive going identification signal for PAL-signals at pin 14, also used for the

automatic colour-killer. SERVICE SWITCH The service switch has two functions. The first position (V

14-3

< 1 V) allows the adjustment of the reference oscillator.

Therefore the colour is switched on and the burst for the oscillator PLL is switched off. The second position (V

14-3

> 5V)

switches the colour on and the output signals can be observed. SANDCASTLE PULSE DETECTOR Sandcastle pulse detector for burst-gate, line and blanking (horizontal and vertical) pulse detection. The vertical part of

the sandcastle pulse is needed for the internal colour-on and colour-off delay. PULSE PROCESSING PART Pulse processing part which shall prevent a premature switching on of the colour. The colour-on delay, two or three field

periods after identification of the PAL signal, is achieved by a counter. The colour is switched off immediately or at the latest one field period after disappearance of the identification voltage.

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.
