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 transmitter, such as
a key fob transmitter, to operate over a long distance.
In terms of temperature, the HT6P2x5A can operate
from -10˚C to 50˚C with very little frequency drift.
Additionally the devices are extremely easy to use
and having a fully integrated oscillator require only
a minimum of external components to implement a
complete and versatile transmitter. For longer distance
remote control, the devices operate together with an
ASK/OOK – Amplitude Shift Keying/On-Off Keyed
– UHF wide-band super-regenerative receiver.
