High Sensitivity, Long Range,
1.5-72kbps, 2.4GHz FSK
Transceiver
General Description
Features
The EM9209 is a 1.5kbps to 72kbps low-power, low-voltage, single
chip 2.4GHz ISM band RF transceiver ideal for battery operated
wireless applications such as wireless sensors and control, gaming,
human interface devices, and security networks.
I Low Voltage:
· 1.9V to 3.6V battery operation
The EM9209’s built-in custom low power micro-controller supports
the proprietary wireless protocol links in the license-free 2.4000GHz
to 2.4835GHz ISM band. It includes a low-IF receiver architecture
and uses FSK modulation. A SPI interface provides a simple control
of the baseband using an external host controller.
The EM9209 provides two communication modes with normal or
high sensitivity for Long Range links and programmable bit rate from
1.5kbps to 72kbps.
The EM9209 provides a divided clock output programmable at either
32.5kHz, 325kHz or 3.25MHz to drive external micro-controllers time
reference.
I Low Power:
· 7mA in RX normal sensitivity mode (NS)
· 8mA in RX high sensitivity mode (HS)
· TX Mode: 11mA @-1dBm, 36mA @+10dBm
· <150µA in Stand-by Mode
· <10nA in Power Down Mode
I High Performance:
· -115dBm sensitivity at 1.5kbps
· +10dBm maximum received input signal
· Programmable output power from -20dBm to
+10dBm
I Ultra compact radio design with low BOM cost:
· COB with 4mm x 4mm footprint
I Operating Temperature: -40°C to +85°C
Applications
I Direct antenna interface (200 Ω differential)
