Function

VSSA

-

1

Analog Ground.

VCO

I/O

2

Voltage Control Oscillator. This pin is used to control the internal oscillator

frequency by DC voltage input from an external low pass filter.

RP

I/O

3

Bias Resistor. The bias resistor is used to regulate the bias current for the

internal oscillator to resonate at the specific dot frequency.

VDDA

-

4

Analog Power Supply. Positive 5 V DC supply for internal analog circuitry.

A 0.1uF decoupling capacitor should be connected across to VDDA and

VSSA as close to the device as possible.

HFLB

I

5

Horizontal Input. This pin is used to input the horizontal synchronizing

signal. It is triggered by a negative edge and has an internal pull-up resistor.

SSB

I

6

the SPI bus is enabled.

SDA

I

7

Serial Data Input. The external data transfers through this pin to the internal

display and control registers. It has an internal pull-up resistor.

SCK

I

8

Serial Clock Input. Clock input pin used to synchronize transferring of data.

It has an internal pull-up resistor.

VDD

-

9

Digital Power Supply. Positive 5 V DC supply for internal digital circuitry. A

0.1uF decoupling capacitor should be connected across to VDD and VSS as

close to the device as possible.

VFLB

I

10

Vertical Input. This pin is used to input the vertical synchronizing signal. It is

negatively triggered and has an internal pull-up resistor.

HTONE

O

11

Half Tone Output. This pin is used to attenuate external R,G,B amplifiers

for a transparent windowing effect.

FBKG

O

12

Fast Blanking Output. Used to cut off external R,G,B signals while

the chip is displaying characters or windows.

BOUT
