DESCRIPTION
The SN55LVCP22 is a 2×2 crosspoint switch
providing greater than 1000 Mbps operation for each
path. The dual channels incorporate wide common-
mode (0 V to 4 V) receivers, allowing for the receipt
of LVDS, LVPECL, and CML signals. The dual
outputs are LVDS drivers to provide low-power, low-
EMI, high-speed operation. The SN55LVCP22
provides a single device supporting 2:2 buffering
(repeating), 1:2 splitting, 2:1 multiplexing, 2×2
switching, and LVPECL/CML to LVDS level
translation on each channel. The flexible operation of
the SN55LVCP22 provides a single device to support
the redundant serial bus transmission needs (working
and protection switching cards) of fault-tolerant switch
systems found in optical networking, wireless
infrastructure, and data communications systems. TI
offers additional gigabit repeater/ translator and
crosspoint products in the SN65LVDS100 and
SN65LVDS122.
The SN55LVCP22 uses a fully differential data path
to ensure low-noise generation, fast switching times,
low pulse width distortion, and low jitter. Output
channel-to- channel skew is 80 ps (typ) to ensure
accurate alignment of outputs in all applications. Both
SOIC and TSSOP package options are available to
allow easy upgrade for existing solutions, and board
area savings where space is critical.
