DESCRIPTION

The SN65LVCP22 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 SN65LVCP22

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 SN65LVCP22 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 commu- nications systems. TI offers additional gigibit repeater/ translator and

crosspoint products in the SN65LVDS100 and

SN65LVDS122.

The SN65LVCP22 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 less than 10 ps (typ) and

50 ps (max) 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.
