Micrel NOT REMENDED FOR NEW DESIGNS ULTRA PRECISION 8:1 MUX WITH INTERNAL TERMINATION AND 1:2 400m V LVPECL FANOUT BUFFER Precision Edge™ Precision ESd Yg5e8™039U Features - Selects between 1 of 8 inputs, and provides 2 precision, low skew LVPECL output copies - Ultra-low jitter design: - 80fsrms phase jitter (typ) - Guaranteed AC performance over temperature and voltage: - DC to 5Gbps throughput - <490ps propagation delay IN-to-Q (VIN > 100m V) - <85ps tr / tf time - <15ps skew (output-to-output) - Unique, patent-pending, channel-to-channel isolation design provides superior crosstalk performance - Unique, patent-pending, input termination and VT pin accepts DC- and AC-coupled inputs (CML, PECL, LVDS) - 400m V LVPECL output swing - Power supply 2.5V ±5% or 3.3V ±10% - - 40°C to +85°C temperature range - Available in 44-pin (7mm ∗ 7mm) QFN package DESCRIPTION Precision Edge™ The SY58039U is a low jitter, low skew, high-speed 8:1 multiplexer with a 1:2 differential fanout buffer optimized for precision tele and enterprise server distribution applications. The SY58039U distributes clock frequencies from DC to 4GHz, and data rates to 5Gpbs guaranteed over temperature and voltage. The SY58039U differential input includes Micrel’s unique, 3-pin input termination architecture that directly interfaces to any differential signal (AC- or DC-coupled) as small as 100m V without any level shifting or termination resistor networks in the signal path. The outputs are 400m V, 100Kpatible LVPECL with extremely fast rise/fall times guaranteed to be less than 85fs. The SY58039U Features a patent-pending isolation design that significantly improve channel-to-channel crosstalk performance. The SY58039U operates from a 2.5V ±5% or 3.3V ±10% supply and is guaranteed over the full industrial temperature range of - 40°C to +85°C. The SY58039U is part of Micrel’s high-speed, Precision Edge™ product line. Data sheets and support documentation can be found on Micrel’s web...
