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 gigibit 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.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during
storage or handling to prevent electrostatic damage to the MOS gates.
