SY58609U
4.25Gbps Precision, CML 2:1 MUX with Internal Termination and Fail Safe Input
General Description
The SY58609U is a 2.5/3.3V, high-speed, fully differential CML 2:1 MUX capable of processing clock signals up to 2.5GHz and data patterns up to 4.25Gbps. The SY58609U is optimized to provide a buffered output of the selected input with less than 20ps of skew and less than 10pspp total jitter.
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) as small as 100mV (200mVpp) without any level-shifting or termination resistor networks in the signal path. For AC-coupled input interface applications, an integrated reference voltage (VREF-AC) is provided to bias the VT pin.
