GENERAL DESCRIPTION
The ADN4605 is a 40 × 40 asynchronous, protocol agnostic, digital crosspoint switch, with 40 differential PECL/CML compatible inputs and 40 differential programmable CML outputs.

FEATURES
    DC to 4.25 Gbps per port NRZ data rate
    Adjustable receive equalization 3 dB, 6 dB, or 12 dB boost Compensates over 40 inches of FR4 at 4.25 Gbps
    Adjustable transmit preemphasis/deemphasis Programmable boost and output level Compensates over 40 inches of FR4 at 4.25 Gbps
    Low power 105 mW per channel at 2.5 V (400 mV p-p differential output level swing)
    40 × 40, fully differential, nonblocking array Double rank connection programming with dual maps
    Low jitter, typically <25 ps
