    SY89228U
    1GHz Precision, LVPECL 3, 5 Clock Divider
    with Fail-Safe Input and Internal Termination General Description
    The SY89228U is a precision, low jitter 1GHz 3, 5
    clock divider with an LVPECL output. A unique FailSafe Input (FSI) protection prevents metastable
    output conditions when the input clock voltage swing
    drops significantly below 100mV or input is removed.
    The differential input includes Micrel’s unique, 3-pin
    internal termination architecture that allows the input
    to interface to any differential signal (AC-or DCcoupled) as small as 100mV (200mVPP) without any
    level shifting or termination resistor networks in the
    signal path. The outputs are 800mV, 100Kcompatible LVPECL with fast rise/fall times
    guaranteed to be less than 270ps.
    The SY89228U 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
    SY89228U is part of Micrel’s high-speed, Precision
    ®
    Edge product line.
    All support documentation can be found on Micrel’s
    web site at: www.micrel.com. Block Diagram Precision Edge ® Features Accepts a high-speed input and provides a precision
    3 and 5 sub-rate, LVPECL output Fail-Safe Input
    – Prevents oscillations when input is invalid Guaranteed AC performance over temperature and ...
