3 Description

The SN55LVCP22 is a 2×2 crosspoint switch

providing greater than 1000 Mbps operation for each

path. The dual channels incorporate wide commonmode

(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, highspeed

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.

The SN55LVCP22 uses a fully differential data path to

ensure low-noise generation, fast switching times, low

pulse width distortion, and low jitter. Output channelto-

channel skew is 80 ps (typ) to ensure accurate

alignment of outputs in all applications.
