TDA8359J

RM calculation

Most Philips brand TV signal processors have outputs in

the form of current. This current has to be converted to a

voltage by using resistors at the input of the TDA8359J

(RCV1 and RCV2). The differential voltage across these

resistors can be calculated by:

For calculating the measuring resistor RM, use the

differential input voltage (Vi(dif)(p-p)). This voltage can also

be measured between pins INA and INB (see Fig.5). The

calculation for RM is:

EXAMPLE

Measured or given values: II(bias) = 400 µA; Ii1(p-p) =Ii2(p-p)=

290

µA.

The differential input voltage will be:

Supply voltage calculation

For calculating the minimum required supply voltage,

several specific application parameter values have to be

known. These parameters are the required maximum

(peak) deflection coil current Icoil(peak), the coil impedance

Rcoil and Lcoil, and the measuring resistance of RM. The

required maximum (peak) deflection coil current should

also include overscan.

The deflection coil resistance has to be multiplied by 1.2 in

order to take account of hot conditions.

Chapter “Characteristics” supplies values for voltage

losses of the vertical output stage. For the first part of the

scan, the voltage loss is given by Vloss(1). For the second

part of the scan, the voltage loss is given by Vloss(2).

The voltage drop across the deflection coil during scan is

determined by the coil impedance. For the first part of the

scan the inductive contribution and the ohmic contribution

to the total coil voltage drop are of opposite sign, while for

the second part of the scan the inductive part and the

ohmic part have the same sign.

For the vertical frequency the maximum frequency

occurring must be applied to the calculations.

The required power supply voltage VP for the first part of

the scan is given by:

The required power supply voltage VP for the second part

of the scan is given by:

The minimum required supply voltage VP shall be the

highest of the two values VP(1) and VP(2). Spread in supply

voltage and component values also has to be taken into

account.
