GENERAL DESCRIPTION
The ADN4600 is an asynchronous, nonblocking crosspoint switch with eight differential PECL-/CML-compatible inputs with programmable equalization and eight differential CML outputs with programmable output levels and pre-emphasis or de-emphasis. The operation of this device is optimized for NRZ data at rates up to 4.25 Gbps. The receive inputs provide programmable equalization w...
