Advance Information

Single Reference Source E1 to STS-3 with 8 kHz
Reference
The device may operate in freerun mode or with a
single reference source. The 8 kHz output from the
MT9075 is sourced from the clock extracted from the
E1 trunk. It becomes the reference for the PLL which
then generates ST-BUS signals F0o, C4o and C2o to
form the system backplane clock. The MT90840
connects to the system backplane, as well as to an
OC3 link via an STS-3 Framer and optical link. The
19.44 Mhz clock required by the MT90840 is
generated by the MT9044. In the event that the E1
link is broken, the LOS output of the MT9075 goes
high placing the MT9044 in freerun mode.
