The MAX11947 is an AISG v2.0 and v3.0-compliant, fully integrated modem with a 4:1 multiplexer facilitating connectivity between a single modem and up to four RF ports. The MAX11947 receiver offers a typical dynamic range of 20dB and integrates a bandpass filter that operates at the 2.176MHz carrier frequency with a narrow 200kHz bandwidth and is fully compliant with the AISG spectral emission profile. It can modulate OOK signals at the required 9.6kbps and up to 115.2kbps for back compatibility with the older AISG standard. The output power can be varied with an internal register setting from under 0dBm to over +6dBm in order to compensate for loss in the external circuitry and cabling. The receiver sensitivity threshold is also adjustable from the default -15dBm down to less than -20dBm to accommodate power loss through an external splitter. The MAX11947 also features a direction output to facilitate the RS-485 bus arbitration in tower-mounted equipment. The MAX11947 is available in a small, 4mm x 4mm 20-pin TQFN and is rated for operation in the -40°C to +105°C temperature range.

Applications

  • (SALD and MALD)

Product Detail

The MAX11947 evaluation kit (EV kit) includes two fully assembled and tested circuit boards (PCBs) that contain all the components necessary to evaluate the performance and functionality of the MAX11947 AISG V2.0/ V3.0-compliant, fully integrated modem with a 4:1 multiplexer.

The EV kit includes Windows® 10-compatible software that provides a simple graphical user interface (GUI) for controlling the circuit board through a standard USB micro connection. The GUI provides the user access to hard- ware controls through a MAX32625PICO board.

The MAX32625PICO board is a rapid development platform designed to help engineers quickly implement designs with the MAX32625 Arm® Cortex®-M4 microcontroller with FPU. The board also includes the MAX14750 PMIC that can directly power the entire MAX11947EV kit board.

Additional features of the MAX11947 include on board crystal reference, SMA connectors for RF ports, optional component footprints for filter design and an off-board RS485 interface providing 2.75kVRMS of isolation.

Applications

  • 2MHz OOK Modem Applications
