SY89859U Datasheet | Micrel Semiconductor

Precision Low-Power 8:1 MUX with Internal Termination and 1:2 LVPECL Fanout Buffer General Description The SY89859U is a low jitter, low-power, high-speed 8:1 multiplexer with a 1:2 differential fanout buffer Precision Edge® optimized for precision tele and enterprise server Features distribution applications. The SY89859U distributes clock frequencies from DC to >2.5GHz, and data rates - Selects between 1 of 8 inputs, and provides 2 to 2.5Gbps guaranteed over temperature and voltage. precision, low skew 100K-patible LVPECL output copies The SY89859U differential input includes Micrel’s unique, 3-pin input termination architecture that - Low power: 150m W typ. (2.5V) directly interfaces to any differential signal (AC- or - Guaranteed AC performance over temperature and DC-coupled) as small as 100m V (200m Vpp) without voltage: level shifting or termination resistor networks in the - DC to >2.5Gbps signal path. The outputs are 800m V, 100K-patible - DC to >2.5GHz LVPECL with extremely fast rise/fall time guaranteed - <690ps propagation delay to be less than 180ps. - <180ps tr/tf time The SY89859U Features a patent-pending isolation - <20ps skew (output-to-output) design that significantly improves on channel-tochannel crosstalk-induced jitter performance. - .. Unique, patent-pending channel-to-channel isolation design provides superior crosstalk The SY89859U operates from a 2.5V ±5% or 3.3V performance ±10% supply and is guaranteed over the full industrial temperature range of - 40°C to +85°C. The SY89859U - Ultra-low jitter design: is part of Micrel’s high-speed, Precision Edge® product - <1ps RMS random jitter line. - <10ps PP deterministic jitter All support documentation can be found on - <10ps PP total jitter (clock) Micrel’s web site at: .micrel.. - <1ps RMS cycle-to-cycle jitter - <0.7ps RMS crosstalk-induced jitter - Unique, patented input termination and VT pin accepts DC- and AC-coupled inputs (CML, PECL, LVDS) - Power...
