The BCM94201 Satellite Receiver Evaluation System is
intended for use by hardware and software engineers as a
benchmark and development tool for accelerating the BCM4201
system design cycle.
This evaluation system reference design provides the ideal
platform for evaluating the BCM4201 Universal Satellite
Receiver, that supports the Digicipher^TM II, DIRECTV^® and DVB
standards. This design tool is the first system to demonstrate
how lower design costs can be achieved by operating the
BCM4201 in combination with the BCM3440 CMOS tuner.
This compact, stand-alone system provides a complete
development environment for rapid technology integration.
The BCM94201 supports variable data rates from 2-85 Mbps.
Either serial or parallel output mode may be selected. On-
board line drivers simplify system test and integration.
LNB voltage is supplied through the tuner
connector. The BCM3440 tuner interfaces with the BCM4201,
minimizing the need for additional components.
The BCM94201 is delivered with Windows^®-based system
software that communicates with the evaluation system using I²C
protocol via the parallel port. The software contains several
screens providing detailed performance and status information
contained in the BCM4201. These screens include a constellation
display, Signal-to-Noise Ratio (SNR) estimates, Viterbi and
Reed-Solomon performance parameters, and Bit Error Ratio
(BER) estimates that use the on-chip BERT for simplified lab test
set up.
Detailed application notes and a user manual describe the
software operation. Script files are provided to enable easy
configuration of the BCM4201 in every mode of operation. The
user manual includes schematics and a bill of materials for the
reference design. PCB Gerber files are also provided.
