MAX41462GUB+ General Description

The MAX41461/MAX41462 is a UHF sub-GHz ISM/SRD transmitter is designed to transmit On-Off Keying (OOK) or Amplitude-Shift Keying (ASK) data in the 286MHz to 960MHz frequency range. It integrates a fractional phase-locked-loop (PLL), so 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 external microcontroller interface. The only frequency-dependent components required are for the external antenna matching network. Optionally, the device can be put into programmable mode and programmed using an I²C interface. The crystal-based architecture of the MAX41461/MAX41462 eliminates many of the common problems with SAW-based transmitters by providing greater modulation depth, faster frequency settling, higher tolerance of the transmit frequency, and reduced temperature dependence. A clock-out signal at 800kHz is also provided.
