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 commu-
nications 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.
