FEATURES  
DESCRIPTION  
D
High Speed 2x2 LVPECL Crosspoint Switch  
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.

Fast Switch Time of 1.7 ns (Typ)  
Fast Propagation Delay of 0.75 ns (Typ)  
16 lead SOIC and TSSOP Packages  
Operating Temperature: −40°C to 85°C  
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.

(1) The marketing status values are defined as follows:  
ACTIVE: Product device recommended for new designs.  
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.  
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in  
a new design.  
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.  
OBSOLETE: TI has discontinued the production of the device.  
(2)  
Eco Plan - May not be currently available - please check http://www.ti.com/productcontent for the latest availability information and additional  
product content details.  
None: Not yet available Lead (Pb-Free).  
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements  
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered  
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.  
Green (RoHS & no Sb/Br): TI defines "Green" to mean "Pb-Free" and in addition, uses package materials that do not contain halogens,  
including bromine (Br) or antimony (Sb) above 0.1% of total product weight.  
(3)  
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDECindustry standard classifications, and peak solder  
temperature.
