Description

Code Address Pin Nos.0 ~ 5

I

These six tri-state pins are detected by PT2262 to

determine the encoded waveform bit 0 ~ bit 5.

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

Code Address Pin Nos.6 ~ 11/Data Pin Nos.5 ~ 0.

These six tri-state pins are detected by PT2262 to

determine the encoded waveform bit 6 ~ bit 11.

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. PT2262 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

I

Oscillator Pin No.2

determine the fundamental

frequency of the PT2262.

Data Output Pin.

O

The encoded waveform is serially outputted to this

pin. When PT2262 is not transmitting, DOUT

outputs low (Vss) voltage.
