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.
