The MAX9947 is an AISG-compliant, fully integrated
transceiver.
The MAX9947 receiver offers a typical dynamic range of
20dB and integrates a bandpass filter that operates in the
2.176MHz frequency with a narrow 200kHz bandwidth.
The MAX9947 transmitter integrates a bandpass filter
that is compliant with the AISG spectrum emission pro-
file. It can modulate OOK signals up to 115.2kbps. The
output power can be varied with external resistors from
+7dBm to +12dBm to compensate for loss in the external
circuitry and cabling.
The MAX9947 also features a direction output to facilitate
the RS-485 bus arbitration in tower-mounted equipment.
The MAX9947 is available in a small, 3mm x 3mm 16-pin
TQFN and is rated for operation in the -40°C to +85°C
temperature range.
