Description
The TT Series transceiver is designed for
reliable bi-directional, long-range remote
control applications. It consists of a highly
optimized Frequency Hopping Spread
Spectrum (FHSS) RF transceiver and
integrated remote control transcoder. The
FHSS system allows higher power and,
therefore, longer range than narrowband radios. The TT Series transceiver
has obtained modular approval for the United States and Canada.
Eight status lines can be set up in any combination of inputs and outputs
for the transfer of button or contact states. A selectable acknowledgement
indicates that the transmission was successfully received. Operating in
the 902 to 928MHz frequency band, the module is capable of generating
+12.5dBm and achieves a typical sensitivity of -113dBm.
Primary settings are hardware-selectable, which eliminates the need for an
external microcontroller or other digital interface. For advanced features,
optional software configuration is provided by a UART interface; however,
no programming is required for basic operation.
Housed in a compact reflow-compatible SMD package, the transceiver
requires no external RF components except an antenna, which greatly
simplifies integration and lowers assembly costs.
