AD8156 Datasheet Digital Crosspoint Switch

Manufacturer: Analog Devices

General Description

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.

Overview

6.25 Gbps, 4 × 4, Digital Crosspoint Switch with EQ AD8156.
