MxL568C

6CH Single Input Full-Spectrum Capture Satellite Receiver
Product Brief

Description

The MxL568 is a low-power single-chip satellite receiver IC, featuring an L-band Full-Spectrum Capture® (FSC®) tuner and eight demodulators that are compliant with DVB-S, DVB-S2, and DIRECTV legacy standards.

The MxL568 receives signals from the L-band differential RF input from 950 MHz to 2150 MHz, and demodulates eight satellite channels to produce six independent serial TS outputs. All six TS outputs support two-wire, three-wire, or four-wire modes. The MxL568 can accept up to four DVB TS inputs. Each of the six TS output ports can carry TS from any of the internal eight DVB-S/DVB-S2/DIRECTV legacy demodulators, or a TS from one of the four DVB TS inputs.

The MxL568 communicates with satellite LNBs through on-chip DiSEqC and FSK modems.

All major functions are incorporated onto the device, including LNA, channel filters, AGC, adaptive equalizers, PLLs, crystal load capacitors, and demodulators. The MxL568 enables simple, compact board designs with low-power consumption and reduced BOM costs.

The MxL568 is controlled via an I2C interface, and operates using 1.8V and 1.1V core supplies and an I/O supply of 3.3V. The MxL568 is available in a small 10 mm x 10 mm footprint 72-pin QFN package.
