6: TECHNICAL DESCRIPTION

6.6 Monochrome LCD Panel Support

The S1D13505 supports 4 and 8-bit, dual and single, monochrome passive LCD panels. All neces-
sary signals are provided on the 40-pin ribbon cable header J6. The interface signals on the cable are
alternated with grounds to reduce crosstalk and noise.
Refer to Table 3-1, "LCD Signal Connector (J6)," for connection information.

6.7 Color Passive LCD Panel Support

The S1D13505 directly supports 4, 8 and 16-bit, dual and single, color passive LCD panels. All the
necessary signals are provided on the 40-pin ribbon cable header J6. The interface signals on the
cable are alternated with grounds to reduce crosstalk and noise.
Refer to Table 3-1, "LCD Signal Connector (J6)," for connection information.

6.8 Color TFT/D-TFD LCD Panel Support

The S1D13505 supports 9, 12 and 18-bit active matrix color TFT/D-TFD panels. All the necessary
signals can also be found on the 40-pin LCD connector J6. The interface signals on the cable are
alternated with grounds to reduce crosstalk and noise.
When supporting an 18-bit TFT/D-TFD panel, the S1D13505 can display 64K of a possible 256K
colors. A maximum 16 of the possible 18 bits of LCD data are available from the S1D13505. Refer
to the "S1D13505 Hardware Functional Specification" for details.
Refer to Table 3-1, "LCD Signal Connector (J6)," for connection information.

6.9 CRT Support

This evaluation board provides CRT support through the S1D13505's embedded RAMDAC. Refer
to the "S1D13505 Hardware Functional Specification" for details.

6.10 Power Save Modes

The S1D13505 supports one hardware suspend and one software suspend Power Save Mode.

6.11 Adjustable LCD Panel Negative Power Supply

Most monochrome passive LCD panels require a negative power supply to provide between -18V
and -23V (I =45mA). For ease of implementation, such a power supply has been provided as an
out
integral part of this design. The signal VLCD can be adjusted by R29 to supply an output voltage
from -14V to -23V and is enabled/disabled by the S1D13505 control signal LCDPWR#.
Determine the panel's specific power requirements and set the potentiometer accordingly before
connecting the panel.

6.12 Adjustable LCD Panel Positive Power Supply

Most passive LCD passive color panels and most single monochrome 640x480 passive LCD panels
require a positive power supply to provide between +23V and +40V (I
mentation, such a power supply has been provided as an integral part of this design. The signal
VDDH can be adjusted by R23 to provide an output voltage from +23V to +40V and is enabled/dis-
abled by the S1D13505 control signal LCDPWR#.
Determine the panel's specific power requirements and set the potentiometer accordingly before
connecting the panel.
