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.
