Multiple E1 Reference Sources with MT9041B
In this example 8 E1 link framers (MT9074) are
connected to a common system backplane clock
using the MT9041B. Each of the extracted clocks
E1.5o go to a mux which selects one of the eight
input clocks as the reference to the MT9041B. The
clock choice is made by a controller using the loss of
signal pin LOS from the MT9074s to qualify potential
references. In the event of loss of signal by one of
the framers, an interrupt signals the controller to
choose a different reference clock. Disturbances in
the generated system backplane clocks C4b and F0b
are minimized by the phase slope limitations of the
MT9041B PLL. This ensures system integrity and
minimizes
the
effect
of
downstream trunks.
