Product Details

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.


  • Digital video (HDMI, DVI, DisplayPort, 3G/HD/SD-SDI)

  • High-speed serial backplane routing to OC-48 with FEC
  • XAUI, 4x Fibre Channel, Infiniband®, and GbE over backplane
  • Data storage networks
