FUNCTIONAL DESCRIPTION
SY55859L is a dual cross point with excellent pin-to-pin
and part-to-part skew matching. As shown in table 1, based
on the logic value at TTL input SELA0, output QA0 replicates
either input DA0 or DA1. TTL input SELA1 selects whether
output QA1 replicates input DA0 or DA1. As shown in table
2, TTL inputs SELB0 and SELB1 perform similarly for outputs
QB0 and QB1 respectively, choosing between inputs DB0
or DB1.
If the two control inputs are tied together, SY55859L
behaves as a redundant distribution device. Depending on
the state of the combined control inputs, QA0 and QA1 will
both replicate either DA0 or DA1. If the two control inputs
are made the logical complement of each other, the
SY55859L functions as a crosspoint, either sending DA0 to
QA0 and DA1 to QA1, or sending DA0 to QA1 and DA1 to
QA0. The same applies to channel B.
SY85859L
’
s CML outputs are source terminated to 50
individually, 100
differentially. The CML inputs are parallel
terminated, also to 50
. This improves signal integrity. With
all terminations on chip, high-speed interfacing is greatly
simplified, eliminating the need for external termination
passive components. Figures 1 and 2 show the input and
output structures.
