Application Information
General Description
The EL5000A is a high performance 70V TFT-LCD row
driver. It level shifts TTL level timing signals from the video
source into 70V peak to peak output voltage. Its output is
capable of delivering 100mA peak current into 1nF of
capacitive load. It also incorporates logic to control the
output timings. The logic timing control circuit is powered
from 3.3V supply. Figure 15 shows the system block
diagram.
Input Signals
The device performs beside of level transformation also logic
operation between the input signals:
STV - Vertical Sync Timing signal, frequency range around
60Hz
CPV - Horizontal Sync Timing signal, frequency range up
to 166kHz
OE - Output Enable Write Signal, frequency range up to
166kHz
Output Signals
The output signals, CKV and CKVB are generated by
EL5000A internal switches. Figure 16 depicts the simplified
schematic of the output stage and interface.
C
L
capacitors model the capacitive loading appeared at the
inputs of the TFT-LCD panel for the CKV and the CKVB
signals. The C
L
is typically between 1nF and 5nF.
In addition to switches SW1, SW2, SW3, and SW4, a fifth
switch is added to reduce the power dissipation and shape
the output waveform. Figure 17 shows the location of the
additional SW5 switch.
In reality, each switch consists of two such switches, one for
the positive discharge and one for the negative discharge,
see Figure 18.
Due to the actual solid-state construction of the switches, the
capacitors C
L
does not get discharged entirely. The amount
of left over charges depends on the value of the voltages of
V
ON
and V
OFF
on the capacitors.
