2.11.2 Edge-Rate Control
The device used as the backplane driver, SN74GTLPH1655, has a feature by
which the backplane slew rate is adjustable via an external edge-rate-control
(ERC) pin held at 3.3 V (slow) or GND (fast). The ERC is set by the JB3 jumper
located below the bit-selection jumper and has two positions: not connected
is slow, and shorted is fast (see Figure 2–20). The following ERC options are
available:
-
JB3 open
Slow edge rate
-
JB3 shorted
Fast edge rate
