Overview
HT6P235A/HT6P245A Learning RF Encoder without Crystal Features • Operating voltage: 2.
5V~3.
6V • Average operating current ♦♦ ♦♦ General Description The devices are a series of encoders which include a fully integrated 433MHz ASK transmitter for remote control system applications.
They form a highly functionally integrated device series which can be described as true “switch-in, antenna-out” monolithic devices.
The devices encode 24 or 28 bits of address and data information and then serially transmits it via their DOUT pin upon receipt of a transmission enable signal which is provided by data pins, D0~D3 or B0~B1.
The devices also encode the address and data information into a coded waveform which is transmitted out on their PAOUT pin for RF modulation.
Two areas stand out for special attention, those of power delivery and operating temperature.
In terms of power, the HT6P2x5A is capable of delivering +16dBm into a 50Ω load, a power level which enables a small form factor transmitte...
