Overview
HT6P237A/HT6P247A Learning RF Encoder Features • Operating voltage: 2.
0V ~3.
6V • Average Operating Current: ♦♦ ♦♦ General Description 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.
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, th...
