AD8156ABCZ

Signal Switches, Multiplexers, Decoders Overview

The AD8156ABCZ is a high-speed, fully differential digital crosspoint switch manufactured by Analog Devices Inc. It features a 4 × 4 nonblocking array with configurable dual 2 × 2 operation and supports data rates from DC to 6.25 Gbps per channel. The device includes programmable input equalization capable of compensating for over 40 inches of FR-4 backplane loss at maximum speeds. It operates on a single 3.3 V power supply (±10%) with typical power dissipation ranging from 400 mW without equalization to 700 mW with all outputs and equalizers active. Integrated 50 Ω termination impedances are provided at both inputs and outputs.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ABCZ suffix against the manufacturer's current ordering guide to confirm package type and temperature range specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Ensure that the control interface voltage levels match the system logic standards, as the device requires a 3.0 V to 3.6 V supply range for proper operation.

Signal Switches, Multiplexers, Decoders Selection Notes
