DESCRIPTION
The SN65LVCP23 is a 2x2 LVPECL crosspoint
switch. 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 LVPECL drivers to provide
high-speed operation. The SN65LVCP23 provides a
single device supporting 2:2 buffering (repeating),
1:2 splitting, 2:1 multiplexing, 2x2 switching, and
LVDS/CML to LVPECL level translation on each
channel. The flexible operation of the SN65LVCP23
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 an additional gigabit repeater/translator in the
SN65LVDS101.
The SN65LVCP23 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.
