STV7620M includes all the logic and power cir-
cuits necessary to drive column electrodes of a
Plasma Display Panel (P. D. P.). Binary values of
each pixel of the displayed line are loaded into the
shift register by a 6 bit wide (A1 - A6) or 3 bit wide
(A1 - A3) data bus, depending on the configuration
of the
BS
input pin. Data is shifted at each low-to-
high transition of the
CLK
clock.
The forward/reverse (F/R) input is used to select
the direction of the shift register.
The
BS
input sets the configuration of the shift reg-
ister either in 3 x 32 bits or in 6 x 16 bits.
In case of a 3 bit arrangement, A1, A2 and A3 data
bus input pins are used. The 3 shift registers are
loaded with 32 clock pulses. A4, A5 and A6 data
bus pins are the outputs of A1, A2 and A3 shift
registers respectively.
CIRCUIT DESCRIPTION
The maximum frequency of the shift clock is
40MHz. This leads to an equivalent 240MHz serial
shift register for a 6 x 16 bits arrangement.
When the
STB
signal is Low, data are transferred
from the shift register to the latch and the power
output stages.
All the output data are kept memorised and held in
the latch stage when the latch input
STB
is pulled
high.
Vsssub and Vsslog must be connected as close as
possible to the logical reference ground of the ap-
plication.
STV7620M is supplied with a 5 volt power supply.
All the logic inputs can be driven either by 5V
CMOS logic or by 3.3V CMOS logic.
A low EMI function has been implemented: the fall-
ing edge of the outputs has 2 slopes, a smooth
one for 30ns followed by a steeper one.
