General Description
The HT6P20x2T3 is a CMOS LSI encoder designed for remote control system applications. It
encodes 24 bits of information and then serially transmits it via the PAOUT pin upon receipt of
transmission enable (DATApins: D0~D4) signals. In addition, the device offers various packaging for
flexible combination of address/data so as to meet the needs of various applications. Its address/data is
transmitted together with the anti-code bits using an RF transmission medium upon receipt of a trigger
signal.
The device is a high performance, easy to use, single chip ASK Transmitter IC for remote wireless
applications in the 300 to 450MHz frequency band. This transmitter IC is a true ²data-in, antenna-out²
monolithic device and offers high performance in terms of power delivery and operating temperature.
Regarding power, the device is capable of delivering up to 10 dBm into a 50W load, which enables a
small form factor transmitter to operate near the maximum limit of transmission regulations. As for
temperature, the device can operate from -40°C to 85°C whose range is wider than SAW operation
range. Being easy to use, the device only needs a reference frequency (RF carrier frequency divided by
32 times) generated from a crystal with a few additional external parts to create a complete versatile
transmitter. The device operates with ASK/OOK (Amplitude Shift Keying/On-Off Keyed) UHF
receiver types from wide-band super-regenerative radios to narrow-band, high performance
super-heterodyne receivers.

Functional Description
Normal Operation
The devices encode and transmits address/data to a decoder upon receipt of a trigger signal. The
address codes of the device are always transmitted as long as power (VDD) is supplied. The
transmission function of the device is enabled by the D0~D1 pins (active low). The following diagram
