HT6P20B2T3/HT6P20D2T3/HT6P20F2T3 -- 224 Encoder with ASK Transmitter

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 (DATA pins: 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 "data-in, antenna-out" 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.
