GENERAL DESCRIPTION
The S3054 is a high performance 2 x 2 crosspoint
switch. It is designed to minimize jitter accumulation
by providing a high bandwidth fully differential signal
path. A 2 x 2 crosspoint can be used to switch OC-
48 data signals in Dense Wavelength Division Multi-
plexer designs and other high speed serial switch
designs.
The 2 x 2 crosspoint is designed using two 2:1 multi-
plexers. It can be used to fan out and/or multiplex

high speed data signals. The S3054 is compatible
with the AMCC OC-48 clock recovery, MUX/DEMUX
and Crosspoint Switch products. This allows signal
integrity to be maintained throughout the system de-
sign.
Table 1 is a truth table detailing the control of flow
through the S3054. The primary AC parameter of im-
portance is the deterministic jitter or data eye degra-
dation inserted by the crosspoint. The design
minimizes jitter accumulation by using high band-
width, low skew fully differential circuits. This provides
for symmetric rise and fall delays as well as noise
rejection.
