Las Vegas, Nev. – MaxLinear Inc. has announced at the 2014 Consumer Electronics Show (CES) that it has started shipping its MxL5xx family of Full-Spectrum Capture (FSC) tuner-demodulators for DVB-S/S2 satellite television systems. Designed for multi-channel gateways, the MxL5xx devices are touted as the first single-chip Full-Spectrum Capture satellite TV receiver ICs that support single or multiple RF inputs, up to a maximum of four.
The six SoCs in the MxL5xx family of satellite front-end devices also integrate from four up to a maximum of eight DVB-S/S2 demodulators, which enables reception and demodulation of an equal number of digital satellite TV channels simultaneously.
The product family includes two single-input RF receivers, the MxL561, and MxL581, which support six and eight channels, respectively. The family also includes the MxL582, which features two RF inputs and eight channels, and supports extended L-Band (XL-Band) capability for use with two cable wide-band low-noise block (LNB) downconverter systems. Other devices in the family include the MxL544, which supports four RF inputs and provides four DVB-S/S2 channels, and the MxL584, which supports four RF inputs with eight DVB-S/S2 demodulators.
The MxL5xx devices offer a large RF full-spectrum signal capture bandwidth ranging from 1.2 GHz to 4.8 GHz, depending on the RF input configuration. The Full-Spectrum Capture technology enables each demodulator to receive channels at any frequency within the entire capture bandwidth, enabling true multi-screen user experiences, whole-home multi-channel PVRs and fast-channel change capability, said MaxLinear. These devices also provide spectrum analysis data that operators can use for remote performance monitoring and diagnostics from a remote technical service center.
With the MxL5xx family, MaxLinear said it provides satellite OEMs a complete range of low power, CMOS-based, high-performance receiver solutions addressing a variety of applications including home media gateways, SAT>IP multiswitches and IP-LNBs.
The MxL5xx devices integrate all active front-end components, including low-noise amplifiers (LNAs), and each device supports a configurable transport stream interface compatible with the leading MPEG decoder SoCs. "Due to the high levels of system integration, the bill of material (BOM) in end applications is reduced to a minimal number of low-cost passive components, and a crystal, which enables ultra-compact low cost system solutions," said MaxLinear. The devices are available in small form factor, pin-compatible 10- x 10-mm QFN packages.
