B output signals to the low reference current and not on the cut off point of the cathode In this way spreads in the picture tube characteristics will not be taken into account In this condition the settings of the white point control registers subaddress 20H 22H and the cathode drive level bits CL3 CLO in subaddress 42H are added to the settings of the RGB preset gain registers subaddress 23H 25H A black level off set can be made with respect to the level which is generated by the black current stabilization system In this way different colour temperatures can be obtainedforthebrightandthedarkpartofthepicture The black level control is active on the Red and the Green output signal It is also possible to control the black level of the Blue and the Green output signal OFB bit 1 In the Vg2 adjustment mode AVG 1 the black current stabilization system checks the output level of the 3 channels and indicates whether the black level of the highest output is in a certain window WBC bit or below or above this window HBC bit This indication can be read from the status byte 01 and can be used for automatic adjustment of the Vg2 voltage during the production of the TV receiver During this test the vertical scan remains active so that the indication of the 2 bits can be made visible on the TV screen The control circuit contains a beam current limiting circuit and a peak white limiting circuit The control is realised by mean

DX bit The VDXEN bit must be set to 1 for this mode The vertical synchronisation is realised by means of a divider circuit 5 2 7 Horizontal and vertical drive The horizontal drive is switched on and off via the soft start stop procedure The soft start function is realised by means of variation of the TON of the horizontal drive pulses During the soft stop period the horizontal output frequency is doubled resulting in a reduction of the EHT so that the picture tube capacitance can easily be discharged In addition the horizontal drive circuit has low power start up function The vertical ramp generator needs an external resistor and capacitor For the vertical drive a differential output current is available The outputs must be DC coupled to the vertical output stage The IC has the following geometry control functions W Vertical amplitude Vertical slope S correction W Vertical shift W Vertical zoom W Vertical scroll Vertical linearity correction When required the linearity setting for the upper and lower part of the screen can have a different setting W Horizontal shift m EW width EW parabola width EW upper and lower corner parabola correction EW trapezium correction W Horizontal parallelogram and bow correction When the East West geometry function is not required e g for 90 picture tubes the EW output pin can be used for the connection of the AVL capacitor This function is cho
