Description

Code Address Pin Nos.0 ~ 7

I

These ten tri-state pins are detected by PT2264 to

determine the encoded waveform bit 0 ~ bit 9. Each

pin can be set to “0”, “1” or “f” (floating ).

Code Address Pin Nos.8 ~ 11/Data Pin Nos.0 ~ 3.

These four tri-state pins are detected by PT2264 to

determine the encoded waveform bit10, bit11.

I When these pins are used as address pins, they

can be set to “0”, “1”, or “f” (floating).

When these pins are used as data pins, they can be

set only to “0” or “1”.

Transmission Enable.

I Active Low Signal. PT2264 outputs the encoded

waveform to DOUT when this pin is pulled to low.

O Oscillator Pin No.1

A resistor connected

between these two pins

determine the

I Oscillator Pin No.2

fundamental frequency

of the PT2264.

Data Output Pin.

O

The encoded waveform is serially outputted to this

pin. When PT2264 is not transmitting, DOUT

outputs low (VSS) voltage.
