ADN4600:  4.25 Gbps, 8 × 8, Asynchronous Crosspoint Switch

Product 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 with nine settings to compensate for up to 30 in. of FR4 and programmable pre-emphasis with seven settings to compensate for up to 30 in. of FR4 at 4.25 Gbps.

The ADN4600 nonblocking switch core implements an 8 × 8 crossbar and supports independent channel switching through the I2C control interface. Every channel implements an asynchronous path supporting NRZ data rates from dc to 4.25 Gbps. Each channel is fully independent of other channels. The ADN4600 has low latency and very low channel-to-channel skew.

The main application for the ADN4600 is to support switching on the backplane, line card, or cable interface sides of serial links.

The ADN4600 is packaged in a 9 mm × 9 mm, 64-lead LFCSP package and operates from −40°C to +85°C.
