CIRCUIT DESCRIPTION

The STV7610A contains all the logic and the pow-

er circuits necessary to drive the columns of a

Plasma Display Panel (P. D. P.). The binary value

of each pixel of the displayed line is loaded into the

shift register. Data are input in a 6-bit wide data

bus to A1 - A6 input (case of forward shift mode).

Data are shifted at each low to high transition of

the CLK shift clock. After 16 shifts the first data are

available on B1 - B6 outputs. These B1 - B6 out-

puts can be used to cascade several drivers to

perform any horizontal resolution. The forward/

(FOR/

) input is used to select the

direction of the shift register, A1 - A6 and B1 - B6

data bus input/output status is set according to the

selected direction. FOR/

= H, A is an input

and B is an output.

Serial inputs, CLK, STB inputs are Smith trigger in-

puts. If not used in the application, Blanking

(

), Polarity (

are internaly pulled to level

”H”. The maximum frequency of the shift clock is

20 MHz. This leads to an equivalent 120 MHz se-

rial shift register.

On low level of STB, data is transferred from shift

freshed as long as STB is kept high.

Blanking input (

) forces the power outputs to

low level when pulled low. All the power outputs

are set at high level when the Polarity command

(

) is pulled low and the Blanking (

) input

is at high level.

VSSSUB and VSSLOG must be connected as close

as possible to the logical reference ground of the

application.
