The document describes the features and characteristics of Analog Devices' 3.2 Gbps Digital Crosspoint Switch AD8151 Rev. B. The switch is a low-cost 33×17 nonblocking array, with each port supporting a data rate of 3.2 Gbps NRZ. It features a wide power supply range, low power consumption, low jitter, etc., making it suitable for high-speed serial backplane routing, fiber optic network switching, and Fiber Channel LVDS applications.
The AD8151 digital crosspoint switch offers a 33 × 17 fully differential, non‑blocking array that operates at data rates up to 3.2 Gbps per port. It features low power consumption (425 mA with outputs enabled), programmable output current, and CMOS/TTL‑compatible control inputs.
Designed for high‑speed serial backplane routing, SONET OC‑48, fiber‑optic network switching and similar applications, the device is supplied in a 184‑lead LQFP package and operates over a temperature range of 0 °C to 85 °C.
