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.
