Application
The SM3 Timing Module is a
complete system clock module for
Stratum 3 timing applications and
conforms to GR-1244-CORE
(Issue 2), GR-253-CORE (Issue
3), ITU-T G.812 (Type 3) and ITUT G813
(Option 2). Applications
include shared port adapters, data
digital cross connects, ADM’s,
DSLAM’s, multiservice platforms,
switches and routers in TDM,
SDH and SONET environments.
The SM3 Timing Module helps
reduce the cost of your design by
minimizing your development time
and maximizing your control of the
system clock with our simplified
design.
This product is compliant with all
required ROHS specifications.
