Output. This signal is used prior to the Power-up to enable
the line drivers for transmission. The polarity of the signal
is programmable through the nPULSE2 pin.
nPULSE2 floating before Power-up: nTXEN active low
(Default option)
nPULSE2 grounded before Power-up: nTXEN active high
(This option is only available in Backplane Mode)
An external crystal should be connected to these pins.
Oscillation frequency range is from 10 to 20 MHz. If an
external TTL clock is used instead, it must be connected to
XTAL1 with a 390Ω pull-up resistor, and XTAL2 should be
left floating.
+5 Volt Power Supply pin.
Ground pin.
