Micrel, Inc. ULTRA PRECISION DIFFERENTIAL LVPECL 4:1 MUX with 1:2 FANOUT and INTERNAL TERMINATION Precision Edge® Precision ESd Y5g8e0®29U Features United States Patent No. RE44,134 - Selects 1 of 4 differential inputs - Provides two copies of the selected input - Guaranteed AC performance over temperature and voltage: - DC-to-> 5Gbps data rate throughput - < 390ps IN-to-Out tpd - < 110ps tr / tf times - Ultra low-jitter design: - < 10ps PP total jitter (clock) - < 1ps RMS random jitter - < 10ps PP deterministic jitter - < 0.7ps RMS crosstalk-induced jitter - Unique patended input design minimizes crosstalk - Accepts an input signal as low as 100m V - Unique patented input termination and VT pin accepts DC- and AC-coupled inputs (CML, LVPECL, LVDS) - 800m V 100K LVPECL output swing - Power supply 2.5V ±5% or 3.3V ±10% - - 40°C to +85°C temperature range - Available in 32-pin (5mm ∞ 5mm) MLF® package APPLICATIONS Precision Edge® DESCRIPTION The SY58029U is a 2.5V/3.3V precision, high-speed, 4:1 differential multiplexer with 100k LVPECL (800m V) patible outputs, capable of handling clocks up to 4GHz and data streams up to 5Gbps. In addition, a 1:2 fanout buffer provides two copies of the selected inputs. The differential input includes Micrel’s unique, 3-pin input termination architecture that allows customers to interface 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 result is a clean, stub-free, low-jitter interface solution. The outputs are 800m V LVPECL, (100k temperature pensated) with extremely fast rise/ fall times guaranteed to be less than 110ps. The SY58029U operates from a 2.5V ±5% supply or a 3.3V ±10% supply and is guaranteed over the full industrial temperature range...
