EN5520

Quad XLB Input Digital Satellite Channel Stacking Switch
Product Brief

Description

The EN5520 is part of Maxlinear’s second generation low power CMOS digital Channel Stacking Switch (dCSS) product family for MDU switch applications. The EN5520 regulation enables aggregating up to 8.4 GHz of satellite content from four wideband RF inputs to single or dual Lband IF outputs.
 
The device integrates a 32-channel stacking engine that is controlled by an embedded microcontroller. The 32 configurable Channel Select Filters (CSFs) can be allocated to any of the two IF outputs to offer complete flexibility to the operators for distributing multi-channel content over coaxial cable to a single family home or to two Multiple Dwelling Units (MDUs) at the lowest system cost.
 
Each IF output is configurable in channel stacking mode or in legacy L-band bypass mode, and features a dedicated DiSEqC2.x compatible modem for remote control by the subscriber STBs.
