4CH Quad Input Full-Spectrum Capture Satellite Receiver
Product Brief


The MxL544 is a low-power single-chip satellite receiver IC, featuring four L-band Full-Spectrum Capture® (FSC®) tuners and four demodulators that are compliant with DVB-S and DVB-S2.

The MxL544 receives signals from the four independent

L-band RF inputs, each from 950 MHz to 2150 MHz, and demodulates four satellite channels to produce four independent serial TS outputs. All four TS outputs support two-wire or three-wire modes.

The MxL544 communicates with satellite LNBs through on-chip DiSEqC and FSK modems.

All major functions are incorporated onto the device, including LNAs, channel filters, AGC, adaptive equalizers, PLLs, crystal load capacitors, and demodulators. The MxL544 enables simple, compact board designs with low-power consumption and reduced BOM costs.

The MxL544 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 MxL544 is available in a small 10 mm x 10 mm footprint 72-pin QFN package.
