The SY89540U is a low-jitter, low skew, high-speed 4x4 crosspoint switch optimized for precision telecom and enterprise server/storage distribution applications. The SY89540U guarantees data-rates up to 3.2Gbps over temperature and voltage. The SY89540U differential input includes Micrel's unique, 3-pin input termination architecture that directly interfaces to any differential signal (AC- or DC-coupled) as small as 100mV (200mVpp) without any level shifting or termination resistor networks in the signal path.
Provides crosspoint switching between any input pairs to any output pair Patent pending, channel-to-channel isolation design provides superior crosstalk performance Guaranteed AC performance over temperature and voltage: DC-to-3.2Gbps throughput Power supply 2.5V ±5% -40°C to +85°C temperature range Available in 44-pin (7mm x 7mm) QFN package Pb-Free Green package
