SY56040ARMY

The SY56040ARMY is a fully differential, low voltage CML 4x4 crosspoint switch from Microchip Technology. It is designed to process clock signals as fast as 5GHz or data patterns up to 6.4Gbps. The device features Micrel’s unique 3-pin input termination architecture, allowing it to interface with LVPECL, LVDS, or CML differential signals as small as 100mV without external level-shifting or termination resistor networks.

Key electrical specifications include a throughput of DC to 6.4Gbps, typical propagation delay of less than 400ps, and output skew of less than 25ps. Rise and fall times are guaranteed to be less than 80ps. The switch boasts ultra-low jitter performance, with cycle-to-cycle jitter typically under 1psRMS and total jitter under 10psPP.

Operating from a 2.5V ±5% core supply and a 1.2V/1.8V/2.5V ±5% output supply, the SY56040ARMY is guaranteed over the full industrial temperature range of -40°C to +85°C. It is available in a 44-pin MLF® package (7mm x 7mm).

Applications for this crosspoint switch include data distribution for OC-48, SONET, Fibre Channel, and Gigabit Ethernet, making it suitable for markets such as test and measurement, enterprise networking equipment, and high-end servers.
