Holtek Semiconductor HT6P247A
The HT6P2x7A devices form a series of data encoders which include fully integrated ASK transmitters for remote control system applications. These highly integrated devices are true “switch-in, antenna-out” monolithic devices. They encode 22 or 28 bits of information and then serially transmits the data out on their PAOUT pin upon receipt of transmission enable (Data pins: D0~D3 or B0~B1) signals.| Part No. | HT6P247A |

GENERAL DESCRIPTION
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 delivery and operating temperature. In terms of power, the devices are capable of delivering +16 dBm into a 50Ω load. This power level enables a small form factor transmitter such as a key fob transmitter to operate with a maximum distance. In terms of temperature, they can operate from -40˚C to 85˚C with very little frequency drift. They additionally offer exceptional ease of use and can easily pass FCC/ETSI regulations. One only needs a few additional components for harmonic filtering. The devices are used with ASK/ OOK (Amplitude Shift Keying/On-Off Keyed) UHF receiver types from wide-band super-regenerative radios to narrow-band, high performance superheterodyne receivers to form a complete remote system.
