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 into a 50W
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 -40ºC to 85ºC with very little
frequency drift. They additionally offer exceptional
ease of use. One only needs a reference frequency
generated from an external crystal to create a
complete versatile transmitter.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
super-heterodyne receivers.
