Input Connectors and Programmable Jumpers

Table1. Input Connectors and Programmable Jumpers.

Pins Signal Symbol Description

J1(Data/power input connector)

1, 2 Voltage Vcc2 Supply voltage (+11…30V) converted to

required internal high voltages.

3, 4 Voltage Vcc1 Supply voltage (+5 V) for the logic.

5 Enable _ENABLE Display operation is enabled when LOW or

left disconnected.

6,8,10

12,14,16 Ground GND Signal and power return.

7 Two-bit

data

TVID Odd column data input for optional two bit

parallel mode. See page 6.

9 Vertical

Sync

VS The vertical sync signal VS controls the

vertical position of the picture. The topmost

row displayed is the first HS HIGH time

ending after the rising edge of the VS.

11 Horizontal

Sync

HS The horizontal sync signal HS controls the

horizontal position of the picture. The last

320 pixels before the fall of HS are displayed.

13 Video Clock VCLK The VCLK signal shifts data present on the

VID and TVID lines into the display system.

VCLK is active on the rising edge.

15 Video Data VID Signal that supplies the pixel information to

the system. Even pixel data for two pit

parallel mode. See page 6.

J2 (Control input)

1 Luminance LCb Brightness control inputs a and b. If left

disconnected, luminance is at its maximum

level. See brightness control on page 6.

2 Luminance LCb

3 Ground GND Signal return. Same as GND in connector J1.

4 Ground GND Signal return. Same as GND in connector J1.

Pinstrip PS1

1 SELFTEST When set, video data input in VID and TVID is displayed

asynchronously.

2 DCONFIG The video data is input two pixels per video clock using VID

and TVID if jumper is set.
