MxL868

Full Spectrum Capture Satellite Digital ODU IC, 8 Input

Description

The MxL868 is a low-power, single-chip Full- Spectrum Capture™ (FSC™) satellite digital ODU IC, that features eight half L-band inputs (seven 950MHz–1450MHz and one 1650MHz–2150MHz) for an LNBF application. The MxL868 can also be configured for four low half band inputs (950MHz– 1450MHz) and four high half band inputs (1650MHz–2150MHz), with an external diplexer for an MDU application. In each configuration, the MxL868 supports three IF output ports that are configurable as dual-band or triple-band translate modes, or the DCS mode.
 
The MxL868 integrates a host CPU microcontroller, FSK modems and controllers, DiSEqC controllers, and a digital crossbar to support BT and DCS functionality. 
 
All major functions are incorporated onto the chip, which includes broadband input and output filters, LNAs, channel filters, AGC, and PLL. With its high level of integration and low power consumption, the MxL868 enables a true single-chip satellite ODU solution for band translation, high-density DCS LNBs, and MDU switches that require compact board design and low BOM.
 
The MxL868 operates using 1.8V and 1.1V dual supplies. The MxL868 is available in a small 10mm x 10mm2 footprint, 88-pin QFN package.
