Demodulator Factories – ECMM, DOCSIS 3.0, 2xGE, 2xMCX, SA120IE – MoreLink Detail:

Product Detail

The MoreLink’s SA120IE is a DOCSIS 3.0 ECMM Module (Embedded Cable Modem Module) supporting up to 8 downstream and 4 upstream bonded channels to deliver a powerful high-speed Internet experience.

The SA120IE is temperature hardened for integration in other products that are required to operate in the outdoor or extreme temperature environment.

Base on Full Band Capture (FBC) function, SA120IE is not only a Cable Modem, but also can be used as a Spectrum Analyzer.

This product specification covers DOCSIS® and EuroDOCSIS® 3.0 versions of the Embedded Cable Modem Module series of products. Throughput this document, it will be referred as SA120IE.The SA120IE is temperature hardened for integration in other products that are required to operate in the outdoor or extreme temperature environment. Based on Full Band Capture (FBC) function, SA120IE is not only a Cable Modem, but also it can be used as a Spectrum Analyzer (SSA-Splendidtel Spectrum Analyzer). Heatsink is mandatory and application specific. Three PCB holes are provided around the CPU, so that a heatsinking bracket or similar device can be affixed to the PCB, to transfer the generated heat away from the CPU and towards the housing and environment.

Board-to-Board Connectors between Digital and CM Board

There’re two boards: Digital board and CM Board, which use four pairs of board-to-board connectors to transmit RF signals, Digital signals and power.

Two pairs of MCX connectors used for DOCSIS Downstream and Upstream RF Signals. Two pairs of Pin Header/PCB Socket used for Digital Signals and Power. CM board is placed under the Digital Board. CM’s CPU is contacted to the housing through thermal pad to transfer the heat away from CPU and towards the housing and environment.

The mated height between two boards is 11.4+/-0.1mm.

Here’s the illustration of matched board-to-board connection:

Note:

Cause of Board-to-Board design for two PCBA Boards, in order to make sure stable and reliable connection, therefore, when

To design the Housing, it should be taken the assembly engineering and screws for fix into consideration.
