Silicon Laboratories Si5041-EVB Manual

Si5041 E
Description
The Si5041-EVB provides a platform for evaluating
Silicon Laboratories' Si5041 XFP Signal Conditioning
Transceiver. The Si5041 is a complete, low-power, high-
performance XFP transceiver suitable for use in all XFP
module types, from short-reach datacom to long-reach
telecom applications. The Si5041 is unique in that it
integrates a rate-agile, jitter-attenuating transmit CMU
and receive CMU. The device supports referenceless
operation or may use a reference clock for LOL
detection. The device can be completely configured
through a serial microcontroller interface. The Si5041
Transceiver provides full-duplex operation at serial data
rates from 9.95 to 11.35 Gbps (continuous).
The Si5041-EVB also contains an MCU (C8051F320)
and a crystal oscillator (Si534), both from Silicon Labs.
The 8051F320
communication between the Si5041 and the Si5041-
EVB Software. The Si534 is a multi-rate crystal
oscillator that, when enabled, supplies one of four
selectable reference clocks to the Si5041 while
providing that clock at SMA connectors for external
monitoring/use.
The Silicon Laboratories MCU (C8051F320) has a USB
port that is used to communicate to a PC that is running
the Si5041 EVB software. The MCU also has a serial
port that connects to the serial control port of the Si5041
to read and write to its registers. In addition, the MCU
drives all but one of the LEDs on the EVB and can make
a very accurate reading of the three voltages that power
the EVB.

DDIO
Si5041.
 Four selectable on-chip reference frequencies.
 LEDs for visual monitoring of key chip and board
parameters.
 Si5041 EVB software allows for quick and easy
access to all registers in the Si5041.
 A dual-row header allows the Si5041 to be easily
connected to another MCU for serial control and
control
status communications.
 Synchronous output clock at 1/64 the recovered
clock rate.
Si5041-EVB Quick Start
To set up the Si5041-EVB, perform the following steps:
1. Install the Si504x EVB Software. (Assumes that
Microsoft .NET Framework 1.1 is already installed.)
2. Allow the software installer to also install the Si504x
EVB Driver. (This must be installed before the EVB
is connected to the PC via the USB cable.)
3. Connect the power supplies to the EVB.
4. Turn on the power supplies.
5. Connect a USB cable from the EVB to the PC where
the software was installed. Launch the software by
clicking on StartProgramsSilicon
LaboratoriesSi504x EVB Software and selecting
one of the programs to run.
6. If prompted, pick a serial number corresponding to
the desired EVB to control.
