Overview

The HSL femtocell hardware consists of two boards: A digital board with the ARM, DSP and FPGA,
as well as the radio board, containing the ADC/DAC/oscillator/mixer/filter/duplexer.

Both boards are interconnected using a small adapter board. This adapter board also contains
the Ethernet jack (including magnetics).

Digital Board

The digital board contains a placement option for a GPS module

RF board

So far we have only documented those parts that are not under the massive shielding cover.

The RF board contains a placement option for an OCXO.
