With an industry best +6 dBm output power, the MeshConnect IC will support a wide a variety of applications without the
need for external amplification. Combined with a highly sensitive -97 dBm receiver the MeshConnect IC leads the industry
with 103 dB link budget.
In addition to excellent RF performance at 250 kbps data rates, the IC adds high speed modes, Turbo (500 kbps) and
Premium (1 Mbps), for networks looking for increased throughput. The device provides numerous general-purpose I/O pins,
peripheral functions such as timers and UARTs and is one of the first devices to provide an embedded Voice CODEC.
CEL provides its customers with the IEEE 802.15.4 stack as part of the software library. Also available are the hardware &
software tools required to develop custom applications.
The combination of industry leading link budget, high speed RF, and integrate voice CODEC make the IC a truly distinct
single chip solution.
The Extended Range module adds both an PA and LNA to maximize RF performance. The PA enable the Extended Range
module to output up to +20 dBm transmit power. In the receive path the addition of the LNA boosts the already sensitive
receiver up to -103 dBm. The Extended Range link budget boasts a very robust 123 dB enabling a line of sight range over
3 miles.
