With an industry best +8 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 -98 dBm receiver the MeshConnect IC leads the industry
with 106 dB link budget.
In addition to excellent RF performance at ZigBee (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 CEL ZigBee 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 NEC uPG2250 PA enable the
Extended Range module to output up to +20 dBm transmit power. In the receive path the addition of the UPC8233 LNA
boosts the already sensitive receiver up to -103.5 dBm. The Extended Range link budget boasts a very robust 123.5 dBm
enabling a line of sight range over 2 miles.
