General Description
The HT6P4x7A devices form a series of data encoders which include fully integrated ASK transmitters for remote control system applications. These highly integrated chips are true “switch-in, antenna-out” monolithic devices. They encode 24 or 28 bits of information and then serially transmit the data out on their PAOUT pin upon receipt of a transmission enable (Data pins: D0~D3 or B0~B1) signal. They encode address and data information into a coded waveform suitable for modulation and transmission using their integrated RF circuits. The devices offer high performance in two areas: power level and operating temperature. In terms of power level, the devices are capable of delivering +16dBm .
