DB(0:9)
Data Input
Description
10-Bit Data Input. MSB = DB(0:9).
CLK
Clock
Clock Input.
STSQ
Start Sequence
The state of STSQ is detected on the active edge of CLK. A new data loading sequence begins on
the next active edge of CLK after STSQ is detected HIGH.
The active CLK edge is the rising edge when E/O is held HIGH. It is the falling edge when E/O is
held LOW.
R/L
Right/Left Select
A new data loading sequence begins on the left with Channel 0 when this input is LOW, and on
the right with Channel 5 when this input is HIGH.
E/O
Even/Odd Select
The active CLK edge is the rising edge when this input is held HIGH and the falling edge when
this input is held LOW. Data is loaded sequentially on the rising edges of CLK when this input is
HIGH and on the falling edges when this input is LOW.
XFR
Data Transfer
XFR is detected and a data transfer is initiated on a rising CLK edge when this input is held HIGH.
Data is transferred to the video outputs on the next rising CLK edge after XFR is detected.
VID0–VID5
Analog Outputs
These pins are directly connected to the analog inputs of the LCD panel.
V1, V2
Reference Voltages
The voltage applied between these pins set the reference levels of the analog outputs.
VREFHI,
VREFLO
Full-Scale References
The voltage applied between these pins sets the full-scale output voltage.
INV
Invert
When this pin is HIGH, the analog output voltages are above VMID. When LOW, the analog
output voltages are below VMID. VMID is a hypothetical reference level set by the voltages
applied to V1 and V2. VMID is equal to (V1 + V2)/2.
DVCC
Digital Power Supply
Digital Power Supply.
DGND
Digital Supply Return
This pin is normally connected to the analog ground plane.
AVCCx
Analog Power Supplies
Analog Power Supplies.
AGNDx
Analog Supply Returns
Analog Supply Returns.
BYP
Bypass
A 0.1 μF capacitor connected between this pin and AGND ensures optimum settling time.
STBY
Standby
When HIGH, the internal circuits are debiased and the power dissipation drops to a minimum.
