SY89855U Datasheet | Micrel Semiconductor

Precision Low Power Differential LVPECL 4:1 MUX with 1:2 Fanout and Internal Termination General Description ® The SY89855U is a 2.5V/3.3V precision, high-speed, Precision Edge 4:1 differential multiplexer with 100K LVPECL (800m V) Features patible outputs, capable of handling clocks up to - Select 1 of 4 differential inputs 2.5GHz and data streams up to 2.5Gbps. In addition, a 1:2 fanout buffer provides two copies of the selected - Provides two copies of the selected input inputs. - Low power 260m W (VCC = 2.5V) The differential input includes Micrel’s unique, 3-pin - Guaranteed AC performance over temperature and input termination architecture that allows customers to voltage: interface to any differential signal (AC- or DC-coupled) - DC-to->2.5Gbps data rate throughput as small as 100m V without any level shifting or - <410ps In-to-Q tpd termination resistor networks in the signal path. The - <180ps tr / tf times result is a clean, stub-free, low-jitter interface solution. The outputs are 800m V LVPECL, (100K temperature - Ultra low-jitter design: pensated) with fast rise/fall times guaranteed to be - <10ps PP total jitter (clock) less than 180ps. - <1ps RMS random jitter The SY89855U operates from a 2.5V ±5% supply or a - <10ps PP deterministic jitter 3.3V ±10% supply and is guaranteed over the full - <0.7ps RMS crosstalk-induced jitter industrial temperature range of - 40°C to +85°C. For .. - Unique, patent-pending input design minimizes applications that require higher performance, consider crosstalk the SY58029U. The SY89855U is part of Micrel’s high® speed, Precision Edge product line. - Accepts an input signal as low as 100m V All support documentation can be found on Micrel’s web - Unique patented input termination and VT pin site at .micrel.. accepts DC- and AC-coupled inputs (CML, LVPECL, LVDS) Typical Performance - 800m V 100K LVPECL output swing - Power supply 2.5V ±5% or 3.3V ±10% - - 40°C to +85°C temperature range -...
