The Si5040 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 Si5040 is unique in that it integrates a rate-agile, programmable-bandwidth, jitter- attenuating transmit CMU and a fixed-bandwidth receive CMU. The device supports referenceless operation or operation with a synchronous or asynchronous reference clock. The device can be completely configured through a serial microcontroller interface. The Si5040 Transceiver provides full-duplex operation at serial data rates from 9.95 to 11.4 Gbps (continuous). The Si5040-EVB also contains an MCU (C8051F320) and a crystal oscillator (Si534), both from Silicon Labs. The 8051F320 provides status and control communication between the Si5040 and the Si5040- EVB Software. The Si534 is a multi-rate crystal oscillator that, when enabled, supplies one of four selectable reference clocks to the Si5040 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 Si5040 EVB software. The MCU also has a serial port that connects to the serial control port of the Si5040 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. Note that starting in October of 2006, all Si5040-EVBs will be assembled with Si5040 Rev B device on the Si5040 Rev A Printed Circuit Board (PCB). Prior to October of 2006, all Si5040-EVBs were assembled with the Si5040 Rev A device on the Si5040 Rev B Printed Circuit Board (PCB). Features The Si5040-EVB includes the following: Evaluation of Silicon Laboratories' Si5040 XFP Signal Conditioning Transceiver Separate supply connections for the following: VDD (1.8 V) powers the internal circuitry of the Si5040. VDD_3p3 (3.3 V) powers the MCU and XTAL oscillator. VDDIO (1.8 or 3.3 V) powers the LVTTL IOs of the Si5040. Four selectable on-chip reference frequencies. LEDs for visual monitoring of key chip and board parameters. Si5040 EVB software allows for quick and easy access to all registers in the Si5040. A dual-row header allows the Si5040 to be easily connected to another MCU for serial control and status communications. Synchronous output clock at 1/16 the recovered clock rate. Si5040-EVB Quick Start Starting in October of 2006, all Si5040-EVBs will be assembled with the Rev B device. Perform the following steps to set up the Si5040-EVB. 1. Install the Si5040 EVB Driver. (This must be installed before the EVB is connected to the PC via the USB cable.) 2. Install the Si5040 EVB Software. (Assumes that Microsoft .NET Framework 1.1 is already installed.) 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. 6. Launch the Si5040 EVB Software by clicking on Start ProgramsSilicon LaboratoriesSi5040 Software Si5040 Register Programmer. The “Select the EVB” window will appear. Simply click OK (for connection with single EVB). |
