Description
In DVI mode, a HIGH level indicates that the link from the transmitter to the SiI861 is active. A
LOW level indicates a “Loss of Sync” condition between the transmitter and the SiI861.
Please refer to the Section 8. PD does not affect this output when operating in pull-down mode

Out
Standby. In non-DVI mode, a HIGH level indicates a standby condition. A LOW level indicates a
normal active condition.
In DVI mode, this pin is PWM0.
Please refer to the Section 8. PD does not affect this output when operating in pull-down mode
SUSPD /

Out
Suspend / Out of Range. In non-DVI mode, a HIGH level indicates a suspend condition. A LOW
level indicates a normal active condition.
In DVI mode, a HIGH level indicates an “Out of Range” condition. A LOW level indicates normal
operation.
Please refer to Section 7. PD does not affect this output.
PWM0
107
Out
Pulse Width Modulation. These pins can be used as the pulse width modulation signal to control
the backlight brightness or volume.
Please refer to the Section 13 for more information. PD# does not affect this output when in pull-
down mode
BUT0+
108
In
These pins are used to monitor pushbuttons, which can directly control the PWM0 and PWM1
outputs. BUT0+/- are used for PWM0 control, and BUT1+/- are used for PWM1 control. These
pins have internal 100K pull-down resistors.
XCLK
161
In
External clock input. See Section 6 External Clock Rate and Input Frame Rate
XTAL1
154
In
External crystal input to the inverting oscillator amplifier or clock oscillator input.
This sets the output clock frequency to the panel, which will equal this frequency or be 5 times this
frequency if the clock multiplier is used. This pin is 5V tolerant.
See Section 6 External Clock Rate and Input Frame Rate.
XTAL2
155
Out
Output from inverting oscillator amplifier when using on-chip crystal oscillator.
No-connect when using external clock.
RESET#

In R
eset (active LOW). When this pin is pulled LOW, the SiI861 will enter a reset state. When RESET
goes HIGH, the SiI861 begins loading the internal I2C registers automatically from the external
configuration EEPROM.

ADE
70
Out
An external DE signal is generated based on the parallel input IN_HSYNC and IN_VSYNC pins. If
using an external component that does not generate DE, such as a TV decoder, this signal should
be connected externally to IN_DE. The timing of this signal is controlled by the “DE Generation”
registers explained on page 94.
