DESCRIPTION
The SCAN90CP02 is a 1.5 Gbps 2 x 2 LVDS
crosspoint switch. High speed data paths and flow-
through pinout minimize internal device jitter, while
configurable 0/25/50/100% pre-emphasis overcomes
external ISI jitter effects of lossy backplanes and
cables. The differential inputs interface to LVDS and
Bus LVDS signals such as those on TI's 10-, 16-, and
18- bit Bus LVDS SerDes, as well as CML and
LVPECL. The SCAN90CP02 can also be used with
ASICs and FPGAs. The non-blocking crosspoint
architecture is pin-configurable as a 1:2 clock or data
splitter, 2:1 redundancy mux, crossover function, or
dual buffer for signal booster and stub hider
applications.
Integrated IEEE 1149.1 (JTAG) and 1149.6 circuitry
supports testability of both single-ended
LVTTL/CMOS and differential LVDS PCB
interconnect. The 3.3V supply, CMOS process, and
LVDS I/O ensure high performance at low power over
the entire industrial -40 to +85°C temperature range.
