The AD8156, a member of the Xstream line of products, is a high speed, fully differential, digital crosspoint switch. The part can function as a 4 × 4 crosspoint switch with double-latched memory, allowing simultaneous updates, or as a dual 2 × 2 with direct output control. The AD8156 has low power dissipation, typically 700 mW on 3.3 V with all outputs and input equalizers active. It operates at any data rate from dc to 6.25 Gbps per port.

Each input channel on the AD8156 has a programmable input equalizer to compensate for signal loss over a backplane.

The AD8156 high speed inputs are compatible with both ac-coupled and dc-coupled 3.3 V, 2.5 V, or 1.8 V CML, as well as 3.3 V LVPECL data levels. The control interface is LVTTL- and LVCMOS-compatible at 3.3 V. All input and output termination resistors are integrated for ease of layout and to minimize impedance mismatch. Input equalization and unused outputs can be individually disabled to minimize power dissipation.

The AD8156 is packaged in a 49-ball, 8 mm × 8 mm, BGA package with a 1 mm ball pitch. It operates over the industrial temperature range of −40°C to 85°C.
