SY54023ARMG

Signal Switches, Multiplexers, Decoders Overview

The SY54023ARMG is a fully differential, low voltage 1.2V/1.8V CML 2x2 crosspoint switch manufactured by Microchip Technology under the Micrel brand. It processes clock signals up to 3.2GHz or data patterns up to 3.2Gbps. The device operates from a 2.5V ±5% core supply and a 1.8V or 1.2V ±5% output supply. It features an internal 3-pin input termination architecture that interfaces with LVPECL, LVDS, or CML differential signals without external level-shifting networks. The component is housed in a 16-pin MLF package measuring 3mm x 3mm x 0.8mm and is guaranteed over the industrial temperature range of –40°C to +85°C.
