General Description
The HT6P20X2 series of devices are signal encoders designed for remote control system
applications. The devices are capable of encoding 24 bits of information and then serially
transmitting the data on their output pin. A signal transmission is automatically activated when
any of the data input lines change from high to low. The device generates a signal on its output pin
which is composed of a pilot signal, address codes, data codes and an end code. This can be sent
to RF transmitter circuits for wireless transmission. Various configurations of address and data bits
can be chosen according to which device is selected. As all functions are integrated into the device,
the simple addition of switches and RF module is that is required to implement a full RF encoder
function. .
