High Level Interface
This interface is dynamic and allows the user to view and control a variety of functions in the LMH1297
concurrently. In this page, the user can easily control functions such as the following:
•
Configure the LMH1297 as CD or EQ Mode
•
Power Up or Down Different Output Channels
•
Modify the Signal Output from the Output Mux
•
Reset the CDR
•
Change the IN0 CTLE Index Boost Value
NOTE:
Configuration pins
SDI_OUT_SEL
,
OUT0_SEL
, and
EQ_CD_SEL
will be overwritten with
the default values displayed on the High Level Page when first loading SigCon Architect.
These configuration pins are also overwritten by the High Level Page values any time the
Apply
button is clicked. By default, SDI_OUT_SEL is powered down, OUT0_SEL is powered
up, and EQ_CD_SEL is set low (EQ Mode) by the GUI.
NOTE:
Right-clicking the
Cable Driver
and
OUT0
blocks in the High Level Page enables a drop-
down menu for the user to select additional output override options such as VOD amplitude,
pre-emphasis, or de-emphasis controls.
