ADN4600ACPZ

The ADN4600ACPZ from Analog Devices is an 8x8 asynchronous, nonblocking crosspoint switch designed for high-speed serial link applications. It supports NRZ data rates from DC up to 4.25 Gbps, making it suitable for interfaces like FibreChannel, XAUI, Gigabit Ethernet, 10GBase-CX4, and InfiniBand.

Key electrical features include programmable receive equalization and transmit pre-emphasis/de-emphasis, which can compensate for signal degradation over FR4 traces up to 30 inches at 4.25 Gbps. The device operates with a flexible 1.8 V to 3.3 V core supply and consumes low power, approximately 125 mW per channel at 4.25 Gbps. It supports both DC- and AC-coupled differential CML inputs and offers programmable CML output levels with 50 Ω on-chip termination.

The ADN4600ACPZ provides a fully buffered signal path, supporting multicast and broadcast operations. It features independent channel switching controlled via an I2C interface, ensuring low latency and minimal channel-to-channel skew. The device is packaged in a 64-lead LFCSP (9 mm x 9 mm) and operates across a temperature range of -40°C to +85°C.

This crosspoint switch is ideal for backplane, line card, or cable interface applications requiring flexible and high-performance signal routing.
