GENERAL DESCRIPTION

AD8152 is a member of the Xstream line of products and is a breakthrough in digital switching, offering a large switch array (34 × 34) on very little power, typically 2.0 W. Additionally, it operates at data rates up to 3.2 Gbps per port, making it suitable for Sonet/SDH OC-48 with Forward Error Correction (FEC).

The AD8152’s useful supply voltage range allows the user to operate at LVPECL/CML data levels down to 2.5 V. The control interface is LVTTL or LVCMOS compatible on 2.5 V to 3.3 V.

The AD8152’s fully differential signal path reduces jitter and crosstalk while allowing the use of smaller single-ended voltage swings. It is offered in a 256-ball SBGA package that operates over the industrial temperature range of 0°C to 85°C.
