AD8151:  3.2 Gbps, 33 x 17 Digital Crosspoint Switch

Product Details

AD8151 is a member of the Xstream line of products, offering a breakthrough in digital switching and a large switch array (33 x 17) on very little power -- typically 1.5 W. It also operates at data rates in excess of 3.2 Gbps per port, making it suitable for Sonet OC-48 applications with an 8/10-bit forward-error correction (FEC). Furthermore, the price of the AD8151 makes it affordable enough to be used for lower data rates. The AD8151's flexible supply voltages allow the user to operate with either emitter-coupled logic (ECL) or positive emitter-coupled logic (PECL) data levels, and with 3.3 V for further power reduction. The control interface is CMOS-/TTL-compatible (3 V to 5 V).

Its fully differential signal path reduces jitter and crosstalk, while allowing the use of smaller, single-ended voltage swings.

The AD8151 is offered in a 184-lead LQFP package that operates over the extended commercial temperature range of 0°C to 85°C.
