SY54023R Low Voltage 1.2V/1.8V CML 2x2 Crosspoint Switch with Fail-Safe Inputs, 3.2Gbps, 2.5GHz General Description The SY54023R is a fully differential, low voltage Precision Edge 1.2V/1.8V CML 2x2 Crosspoint Switch with Fail Safe Inputs. The SY54023R can process clock signals as Features fast as 2.5GHz or data patterns up to 3.2Gbps. 1.2V/1.8V CML 2x2 Crosspoint Switch with Fail Safe The differential input includes Micrels unique, 3-pin Inputs input termination architecture that interfaces to LVPECL, Guaranteed AC performance over temperature and LVDS or CML differential signals, (AC- or DC-coupled voltage: from a 2.5V driver) as small as 100mV (200mV ) PP DC-to- > 3.2Gbps throughput without any level-shifting or termination resistor <400ps propagation delay (IN-to-Q) networks in the signal path. For AC-coupled input interface applications, an internal voltage reference is <15ps Output Skew provided to bias the V pin. The outputs are CML, with T <95ps rise/fall times extremely fast rise/fall times guaranteed to be less than Ultra-low jitter design 95ps. <1ps cycle-to-cycle jitter RMS The SY54023R operates from a 2.5V 5% core supply <10ps total jitter PP and a 1.8V or 1.2V 5% output supply and is <1ps random jitter RMS guaranteed over the full industrial temperature range ( <10ps deterministic jitter 40C to +85C). The SY54023R is part of Micrels high- PP speed, Precision Edge product line. High-speed CML outputs Datasheets and support documentation can be found on 2.5V 5% , 1.8/1.2V 5% power supply operation Micrels web site at: www.micrel.com.
