Product Description
The EL5825 provides a versatile method of providing the
reference voltages that are used in setting the transfer
characteristics of LCD display panels.
The V/T (Voltage/Transmission) curve of the LCD panel
requires that a correction is applied to make it linear;
however, if the panel is to be used in more than one
application, the final curve may differ for different
applications.
By using the EL5825, this curve can be changed to optimize
its characteristics according to the required application of the
display product.
Each of the reference voltage outputs can be set with a
10-bit resolution. These outputs are available to within
100mV of the power rails of the EL5825.
As all of the output buffers are identical, it is also possible to
use the EL5825 for applications other than LCDs where 8
voltage references are required that can be set to a 10-bit
accuracy.
Serial Interface
The EL5825 is programmed through a three-wire serial
interface. The start and stop conditions are defined by the
ENA signal. While the ENA is low, the data on the SDI (serial
data input) pin is shifted into the 16-bit shift register on the
positive edge of the SCLK (serial clock) signal. The MSB (bit
15) is loaded first and the LSB (bit 0) is loaded last (see
Table 1). After the full 16-bit data has been loaded, the ENA
is pulled high and the addressed output channel is updated.
The SCLK is disabled internally when the ENA is high. The
SCLK must be low before the ENA is pulled low.
To facilitate the system designs that use multiple EL5825
chips, a buffered serial output of the shift register (SDO pin)
is available. Data appears on the SDO pin at the 16th falling
SCLK edge after being applied to the SDI pin.
To control the multiple EL5825 chips from a single three-wire
serial port, just connect the ENA pins and the SCLK pins
together, connect the SDO pin to the SDI pin on the next
chip. While the ENA is held low, the 16m-bit data is loaded to
the SDI input of the first chip. The first 16-bit data will go to
the last chip and the last 16-bit data will go to the first chip.
While the ENA is held high, all addressed outputs will be
updated simultaneously.
The Serial Timing Diagram and parameters table show the
timing requirements for three-wire signals.
The serial data has a minimum length of 16 bits, the MSB
(most significant bit) is the first bit in the signal. The bits are
allocated to the following functions (also refer to the Control
Bits Logic Table)
Bit 15 is always set to a zero
Bit 14 controls the source of the clock, see the next
section for details
Bits 13 through 10 select the channel to be written to,
these are binary coded with channel A = 0, and channel
H = 7
The 10-bit data is on bits 9 through 0. Some examples of
data words are shown in the table of Serial Programming
