HSTL/PECL/LVDS to HSTL
Clock Driver with LVTTL
Clock Select and Enable
Description
The MC100EP809 is a low skew 1to9 differential clock driver,
designed with clock distribution in mind, accepting two clock sources
into an input multiplexer. The part is designed for use in low voltage
applications which require a large number of outputs to drive precisely
aligned low skew signals to their destination. The two clock inputs are
one differential HSTL and one differential LVPECL. Both input pairs
can accept LVDS levels. They are selected by the CLK_SEL pin
which is LVTTL. To avoid generation of a runt clock pulse when the
device is enabled/disabled, the Output Enable (OE), which is LVTTL,
is synchronous ensuring the outputs will only be enabled/disabled
when they are already in LOW state (Figure 9).
The MC100EP809 guarantees low outputtooutput skew. The
optimal design, layout, and processing minimize skew within a device
and from lot to lot. The MC100EP809 output structure uses open
emitter architecture and will be terminated with 50
W to ground
instead of a standard HSTL configuration (Figure 7). To ensure the
tight skew specification is realized, both sides of the differential output
need to be terminated identically into 50
W even if only one output is
being used. If an output pair is unused, both outputs may be left open
(unterminated) without affecting skew.
Designers can take advantage of the EP809’s performance to
distribute low skew clocks across the backplane of the board. Both
clock inputs may be singleend driven by biasing the nondriven pin
in an input pair (Figure 8).
