General Description
The EL5625 is designed to produce the reference voltages
required in TFT-LCD applications. Each output is
programmed to the required voltage with 11 bits of
resolution. Ref-High and Ref-Low pins determine the high
and low voltages of the output range. These outputs can be
driven to within 50mV of the power rails of the EL5625.
Programming of each output, 18 buffers and 1 Vcom, is
performed using the USB interface.
USB Interface
The EL5625 uses USB interface to control the 18 Gamma
channels and Vcom channel (Figure 7). Software is available
for download on Intersil’s website.
Serial Interface
The EL5625 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.
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).
Bits 15 through 11 select the channel to be written to, these
are binary coded with channel A = 0, and channel R = 17
The 11-bit data is on bits 10 through 0. Some examples of
data words are shown in the table of Serial Programming
