The MAX2141 complete low-power receiver is designed for XM satellite radio applications. To form a complete XM radio, the MAX2141 requires only an active antenna module, a crystal, and a SAW filter. The small number of external components needed makes the MAX2141 platform the lowest cost and the smallest wideband receiver solution available.
The receiver includes a self-contained RF AGC loop and IF AGC loop, effectively providing a total dynamic range in excess of 92dB. Channel selectivity is achieved by the SAW filter and by the on-chip lowpass filters. An integrated fractional-N synthesizer allows fine frequency step, making possible the implementation of a software AFC loop. Additionally, a reference buffer is provided for driving a baseband controller.
An I²C bus-compatible interface programs the MAX2141, providing features such as programmable gains, variable-bandwidth lowpass filter tuning, and various power-down modes.
The MAX2141 is Maxim's 2nd-generation device for XM satellite radio applications. It is a drop-in replacement for the 1st-generation MAX2140. While significantly reducing power dissipation, the MAX2141 adds an optional closed-loop IF power control, standby mode, enhanced reference buffer, and improved RF gain-control accuracy.
The MAX2141 is rated to operate over the -40°C to +85°C extended temperature range and is available in a 7mm x 7mm, 44-pin thin QFN package.
