Texas Instruments DS25MB100
The DS25MB100 device is a signal conditioning 2:1 multiplexer and 1:2 fan-out buffer designed for use in backplane-redundancy or cable driving applications. Each input stage has a fixed equalizer to reduce ISI distortion from board traces. The pre-emphasis levels can be independently controlled for the line-side and switchside drivers.| Part No. | DS25MB100 |

APPLICATIONS
● CPRI/OBSAI 3DESCRIPTION
Signal conditioning features include continuous time linear equalization (CTLE) and programmable output pre-emphasis that enable data communication in FR4 backplane up to 2.5 Gbps. All output drivers have four selectable levels of preemphasis to compensate for transmission losses from long FR4 backplane or cable attenuation reducing deterministic jitter. The internal loopback paths from switchside input to switch-side output enable at-speed system testing. All receiver inputs are internally terminated with 100-Ω differential terminating resistors.
