The S Y54023R i s a f ully d ifferential, l ow v oltage 1.2V/1.8V CML 2x2 Crosspoint Switch with Fail Safe Inputs. The SY54023R can process clock signals as fast as 2.5GHz or data patterns up to 3.2Gbps. The differential input includes Micrel's unique, 3-pin input termination architecture that interfaces to LVPECL, LVDS or CML differential signals, (AC- or DC-coupled from a 2.5V driver) as small as 100mV (200mVPP) without a ny l evel-shifting o r t ermination r esistor networks i n t he s ignal p ath. F or A C-coupled i nput interface applications, an internal voltage reference is provided to bias the VT pin. The outputs are CML, with extremely fast rise/fall times guaranteed to be less than 95ps.
