MxL542C

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

Description

The MxL542C is a low-power single-chip satellite receiver IC, featuring two XL-band Full-Spectrum Capture® (FSC®) tuners and four demodulators that are compliant with DVB-S and DVB-S2, and DIRECTV legacy standards.

The MxL542C receives signals from the two independent XL-band differential RF inputs, each from 250MHz to 2350 MHz with a capture bandwidth of 2.1 GHz, and demodulates four satellite channels to produce four independent serial TS outputs. All four TS outputs support two-wire or three-wire modes.

The MxL542C communicates with satellite LNBs through on-chip DiSEqC and FSK modems.

All major functions are incorporated onto the device, including LNAs, RF splitter, channel filters, AGC, adaptive equalizers, PLLs, crystal load capacitors, and demodulators. The MxL542C enables simple, compact board designs with low-power consumption and reduced BOM costs.

The MxL542C integrates an RF splitter that can be used in conjunction with an MxL582 device to enable a cost-effective implementation of a 12-channel solution. The MxL542C 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 MxL542C is available in a small 10 mm x 10 mm footprint 72-pin QFN package.
