SANAYI BÖL.MANISA/ TURKEY

EXPLANATION:

Bus on the 11AK19Pro chasis. Because our new controller's (SDA555X) supply voltage is 3.3Vdc. and also
eeprom supply is same. It means, IIC_Bus of controller and eeprom need pull-up resistors from 3.3Vdc, the
IIC-Bus of video processor and PLL tuner need pull-up resistors from 5Vdc supply.

we have investigate your special st-by problem, we have seen inclination, some kind of eeprom's top of the
SDA,SCL lines. This type eeproms SDA,SCL pins need more current. Therefore we are decrease eeprom's
pull-up resistors value to 2K7.

PROBLEM: Go to st-by case random condition of 11AK19 chasis.

SOLUTION: Resistors R538, R539 values are replacement from 10K to 2K7.

TECHNICAL DESCRIPTION:

This resistors are pull-up resistors of IIC-Bus line (SDA3 & SCL3). There are two different IIC-

There are special IIC-Bus Converter circuit on the 11AK19P chasis for above cases.

We are using much kind of eeprom supplyer. We haven't any problem mostly eeprom type but when
