Functional Characteristics
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.
