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 profile. 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 +105°C temperature range.
