UG336: Si5396 Evaluation Board User's
Guide
The Si5396J-A-EVB is used for evaluating the Si5396 Any-Frequency, Any-
Ouput, Jitter-Attenuating Clock Multiplier. There is only one EVB for the
Si5396, which is an embedded reference device. There is no EVB for the
external reference grade version for the Si5396-EVB. The device grade and
revision is distinguished by a white 1 inch x 0.187 inch label with the text
"Si5396J-A-EB" installed in the lower left hand corner of the board. (For or-
dering purposes only, the terms "EB" and "EVB" refer to the board and the
kit respectively. For the purpose of this document, the terms are synony-
mous in context.)

    UG336: Si5396 Evaluation Board User's Guide Clock Input Circuits (INx/INxB) 6. Clock Input Circuits (INx/INxB) The Si5396J-A-EVB has eight SMA connectors (IN0/IN0B–IN3/IN3B) for receiving external clock signals. All input clocks are terminated as shown in Figure 6.1 Input Clock Termination Circuit on page 8 below.

  • Page 9: Clock Output Circuits (Outx/Outxb)

    The output signal will have no dc bias. If dc coupling is required, the ac coupling capacitors can be replaced with a resistor of appropriate value. The Si5396J-A-EVB provides an L-network at OUT0/OUT0B output pins for optional output termination resistors. Note that components with schematic “NI” designation are not nor- mally populated.

  • Page 10: External Reference Clock (Xa/Xb) Not Supported

    8. External Reference Clock (XA/XB) Not Supported The Si5396J-A-EVB does not support an external reference clock on XA/XB. The layout for the external XTAL is on the board, but the EVB for this part is an embedded XTAL version only and therefore this circuit should remain disconnected and unused.
