MAX41464 - 300MHz-960MHz (G)FSK Transmitter

Download the MAX41464 datasheet PDF. This datasheet also covers the MAX41463 variant, as both devices belong to the same 300mhz-960mhz (g)fsk transmitter family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX41463/MAX41464 is a UHF sub-GHz ISM/SRD transmitter designed to transmit Frequency-Shift Keying (FSK), or Gaussian (G)FSK (or 2GFSK)  data in the 286MHz to 960MHz frequency range.

Key Features

  • preset modes with pin-selectable frequencies so that only one wire is required for an external microcontroller interface. The only frequency-dependent components required are for the external antenna-matching network.  A buffered clock-out signal at 800kHz is also provided.  Optionally, the device can be put into programmable.

MAX41463/MAX41464 EVALUATION KIT AVAILABLE 300MHz–960MHz (G)FSK Transmitter with I2C Interface General Description The MAX41463/MAX41464 is a UHF sub-GHz ISM/SRD transmitter designed to transmit Frequency-Shift Keying (FSK), or Gaussian (G)FSK (or 2GFSK)  data in the 286MHz to 960MHz frequency range. It integrates a fractional phaselocked-loop (PLL) so that a single, low-cost crystal can be used to generate commonly used world-wide sub-GHz frequencies. The fast response time of the PLL allows for frequency-hopping spread spectrum protocols for increased range and security. The chip also features preset modes with pin-selectable frequencies so that only one wire is required for an external microcontroller interface.
