General Description
The Lontium LT1258 is a quad 2:2 cross-point switch or
splitter with signal conditioning suitable for high-speed
bus applications with data rates up to 12.5 Gbps. The
continuous time linear equalizer (CTLE) of the receiver
provides adjustable boost to compensate up to 25 dB
insertion-loss at 6.25 GHz. The transmitter features a
programmable amplitude voltage levels to be selectable
up to 1200 mVpp and de-emphasis up to 8 dB.
In order to save power consumption, the LT1258 can work
well from 1.8V to 2.5V power supply in external LDO
mode.
The LT1258 can be configured to support PCIe, CAUI-10,
and SAS/SATA, 10G-KR, CPRI or other signaling
protocols.
The LT1258 is fabricated in advanced CMOS process and
implemented in 10mm x 5.5mm QFN54 package.
