Overview
The SN65LVCP22 (LVDS output) and SN65LVCP23 (LVPECL output) are
high-speed 2x2 crosspoint switches. The four different functions that these
crosspoints provide are shown in Figure 1–1. The functions of these
crosspoints are selected via pins SEL0 and SEL1. Control pins EN0 and EN1
enable or disable the outputs. The receiver has a wide input common-mode
voltage range with an ability to accept LVDS, LVPECL and CML signaling
levels.

Figure 1–2 is a picture of the SN65LVCP22/23 EVM. The EVM part number
is SN65LVCP22/23EVM. The EVM comes with the SN65LVCP22D and
SN65LVCP23D (SOIC both) installed. A copy of the datasheet is shipped with
the EVM. The latest version of the datasheet is available from www.ti.com.
