AD8158-EVALZ Datasheet PDF - ADI

●GENERAL DESCRIPTION

●The AD8158 is an asynchronous, protocol-agnostic, quad-lane 2:1 switch with a total of 12 differential CML inputs and 12 differential CML outputs. The signal path supports NRZ signaling with data rates up to 6.5 Gbps per lane. Each lane offers programmable receive equalization, programmable output pre-emphasis, programmable output levels, and loss-of signal detection.

●FEATURES

●  Quad 2:1 mux/1:2 demux

●  Optimized for dc to 6.5 Gbps NRZ data

●  Programmable input equalization

●     Compensates up to 40 inches of FR4

●  Loss-of-signal detection

●  Programmable output pre-emphasis up to 12 dB

●  Programmable output levels with squelch and disable

●  Accepts ac-coupled or dc-coupled differential CML inputs

●  50 Ω on-chip termination

●  1:2 demux supports unicast or bicast operation

●  Port-level loopback

●  Port or single lane switching
