DESIGN FEATURES A 10MB/s Multiple-Protocol Chip Set
Supports Net1 and Net2 Standards
by David Soo
Introduction Typical Application With the increase in multinational
computer networks comes the need
for the network equipment to support
different serial protocols. One solution is to provide a different serial
interface board for each market. This
can become unmanageable as product volume increases. The issues of
board swapping and inventory are
often discounted. Another solution is
to place all of the serial interfaces,
each isolated, on a single board. For
example, when the product is sold
with V.35, the serial cable is mapped
to that section of the board. This
requires a large connector plus signal
routing and board space.
The best solution is to support many
different serial protocols on one connector, but that requires the circuitry
for each serial protocol to share the
same connector pins. At first glance
this may not appear to be difficult. …

DESIGN INFORMATION
Trace A is the time-corrected input
pulse and trace B the residue amplifier output. The light compensation
permits very fast slewing but excessive
ringing amplitude over a protracted
time results. The ringing is so severe
that it feeds through during a portion
of the sample gate off-period, although
no overdrive results. When sampling
is initiated (just prior to the sixth
vertical division) the ringing is seen to
be in its final stages, although still offensive. Total settling time is about
2.8Вµ s. Figure 9 presents the opposite
extreme. Here, a large value compensation capacitor eliminates all ringing
but slows down the amplifier so much
that settling stretches out to 3.3Вµs.
The best case appears in Figure 10.
This photo was taken with the compensation capacitor carefully chosen
for the best possible settling time.
Damping is tightly controlled and settling time goes down to 1.7Вµ s. A = 5V/DIV Settling Times
of Various Amplifiers
The previous results, using the
LT1468 amplifier, provide extremely …
