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.
The ADN4605 is optimized for NRZ signaling with data rates of
up to 4.25 Gbps per port. Each port offers adjustable levels of
input equalization, programmable output swing, and output
preemphasis/deemphasis.

The ADN4605 nonblocking switch core implements a 40 × 40
crossbar and supports independent channel switching through
serial and parallel control interfaces. The ADN4605 has low
latency and very low channel-to-channel skew.
An I2C, SPI, or parallel interface is used to communicate with
the device for control of connectivity and other features.
The ADN4605 is assembled in a 35 mm × 35 mm, 352 BGA
package and operates over a temperature range of −40°C
to +85°C.
