CIRCUIT DESCRIPTION
The STV7612 contains all the logic and the power
circuits necessary to drive the columns of a Plas-
ma 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/
re-
verse
(F/
R
) input is used to select the direction of
the shift register, A1 - A6 and B1 - B6 data bus in-
put/output status is set according to the selected
direction. F/
R
= 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 (
BLK
),
Polarity (
POL
are internally pulled to level “H”. The
maximum frequency of the shift clock is 20 MHz.
This leads to an equivalent 120 MHz serial shift
register.
On low level of STB, data is transferred from shift
register to the latch stage. Data will not be re-
freshed as long as STB is kept high.
Blanking input (
BLK
) forces the power outputs to
low level when pulled low. All the power outputs
are set at high level when the Polarity command
(
POL
) is pulled low and the Blanking (
BLK
) input is
at high level.
V
SSSUB
and V
SSLOG
must be connected as close
as possible to the logical reference ground of the
application.
