Overview
The ADN4600ACPZ, produced by Analog Devices Inc., is an asynchronous, nonblocking crosspoint switch designed for high-speed data transmission. This device features eight differential PECL-/CML-compatible inputs with programmable equalization and eight differential CML outputs with programmable output levels and pre-emphasis or de-emphasis. It is optimized for nonreturn-to-zero (NRZ) data rates up to 4.25 Gbps, making it suitable for various high-speed serial link applications.
