UG334: Si5394 Evaluation Board User s Guide The Si5394 EVB is used for evaluating the Si5394 Any-Frequency, Any-Output, Jitter- Attenuating Clock Multiplier. There are four different EVBs for the Si5394. There is a KEY FEATURES Grade A and Grade P board which both require an external reference. There is also a Grade J and Grade E board which have a reference internal to the chip. This user Si5394A-A-EVB for evaluating external guide is intended for all versions of the Si5394 EVBs. The term Si5394 EVB is inclusive reference versions Si5394A/B/C/D of all four different evaluation boards. The device grade and revision is distinguished by Si5394J-A-EVB for evaluating internal a white 1 inch x 0.187 inch label installed in the lower left hand corner of the board. reference versions Si5394J/K/L/M In the example below, the labelSI5394A-A-E indicates the evaluation board has Si5394P-A-EVB for evaluating external been assembled with an Si5394 device, Grade A, Revision A, installed. (For ordering reference (precision grade) purposes only, the terms EB and EVB refer to the board and the kit respectively. For Si5394E-A-EVB for evaluating internal the purpose of this document, the terms are synonymous in context.) reference (precision grade) Powered from USB port or external power supply Onboard 48 MHz XTAL or Reference SMA Inputs allow holdover mode of operation on the Si5394 Grade A and P ClockBuilder Pro (CBPro) GUI programmable VDD supply allows device to operate from 3.3 V, 2.5 V, or 1.8 V CBPro GUI programmable VDDO supplies allow each of the 4 outputs to have its own power supply voltage selectable from 3.3V, 2.5V, or 1.8 V CBPro GUI-controlled voltage, current, and power measurements of VDD and all VDDO supplies Status LEDs for power supplies and control/ status signals of Si5394 SMA connectors for input clocks, output clocks, and optional external timing reference clock to be used on external reference grades only Skyworks Solutions, Inc.
