描述 Description

The MxL251 is an ultra low-power, single-chip receiver IC that is compliant with all global digital-cable standards, including ITU-T J.83 Annex A (DVB-C), Annex B (US Cable), Annex C, SCTE40, SCTE55-1, SCTE55-2, and OC-SP-CCIF2.0.

Featuring dual integrated tuner/demodulators, the MxL251 can receive signals from two independent 6MHz or 8MHz channels over 44MHz to 1002MHz from a single RF input and simultaneously demodulate them producing two independent MPEG Transport Streams (TSs).

特性 Features

·Dual integrated tuner/demodulators can be independently tuned over the entire 44MHz to 1002MHz cable spectrum
·Supports OOB signals from 70MHz to 130MHz
·Programmable channel bandwidths of 6MHz and 8MHz
·Integrated channel filtering eliminates the need for external SAW filters
·On-chip crystal load capacitors reduce BOM costs
·Built-in SPLT facilitates the cascading of devices for additional TSs
·LT output enables RF pass-through
·Reference clock output supports additional receivers in multi-channel applications
·Supports coexistence with MoCA when using an external Low-Pass Filter (LPF)
·High accuracy input power reporting
·Ultra-low power consumption
·Convenient I2C interface

應用 Application

·Set-top boxes (STBs)
