    GENERAL DESCRIPTION
    The DS26303 is an 8-channel short-haul line
    interface unit (LIU) that supports E1/T1/J1 from a
    single
    3.3V
    power
    supply.
    A
    wide
    variety
    of
    applications
    are
    supported
    through
    internal
    termination or external termination. A single bill of
    material can support E1/T1/J1 with minimum external
    components.
    Redundancy
    is
    supported
    through
    nonintrusive
    monitoring,
    optimal
    high-impedance
    modes,
    and
    configurable
    1:1
    or
    1+1
    backup
    enhancements. An on-chip synthesizer generates the
    E1/T1/J1 clock rates by a single master clock input of
    various frequencies. Two clock output references are
    also offered.
