21kHz and can be output to the OSC pin. In a 2 chip system, if
the driving loads are stable, one chip may be programmed to
use the internal oscillator; then the OSC pin will output the clock
from the internal oscillator. The second chip may have the OSC

TRANSFER FUNCTION
The transfer function is:
data
1024
where data is the decimal value of the 10-bit data binary
input code.
The output voltages from the EL5226 and EL5326 will be
derived from the reference voltages present at the V REFL
and V REFH pins. The impedance between those two pins is
about 32k ? .
Care should be taken that the system design holds these two
reference voltages within the limits of the power rails of the
EL5226 and EL5326. GND < V REFH ≤ V S and GND ≤ V REFL ≤
V REFH .
In some LCD applications that require more than 12
channels, the system can be designed such that one
EL5226 or EL5326 will provide the Gamma correction
voltages that are more positive than the V COM potential. The
second EL5226 or EL5326 can provide the Gamma
correction voltage more negative than the V COM potential.
The Application Drawing shows a system connected in this
way.
CLOCK OSCILLATOR
The EL5226 and EL5326 require an internal clock or external
clock to refresh its outputs. The outputs are refreshed at the
9
For transient load application, the external clock Mode
should be used to ensure all functions are synchronized
together. The positive edge of the external clock to the OSC
pin should be timed to avoid the transient load effect. The
Application Drawing shows the LCD H rate signal used, here
the positive clock edge is timed to avoid the transient load of
the column driver circuits.
After power on, the chip will start with the internal oscillator
mode. At this time, the OSC pin will be in a high impedance
condition to prevent contention. By setting pin 32 to high, the
chip is on external clock mode. Setting pin 32 to low, the chip
is on internal clock mode.
