SY89464 Datasheet, PDF (8/10 Pages) Micrel Semiconductor – Precision LVPECL/LVDS Runt Pulse Eliminator 1:10 Fanout Buffer with 2:1 MUX

Micrel, Inc.
SY89464/465U Evaluation Board
terminated with a 50Ω termination-to-ground at
the SMA on the board.
9. Turn on the power and verify the current is
<200mA.
10. Enable the signal source and monitor the
outputs.
Note:
If EN is driven from an external signal, remove R15 and add R16. Do
not leave EN floating. To enable the outputs, connect EN to V_CC or
connect to V_EE to disable the outputs.
Evaluation Board Layout
PC Board Layout
The evaluation board is constructed with Rogers 4003
material, coplanar in design, fabricated to minimize
noise, achieve high bandwidth and minimize crosstalk.
