The 8473 & 8500 have been optimized to work with
the Semtech Chip ACS8510 SETS to meet the
requirements of Bell Core specification GR-1244CORE.
The 8473 & 8500 have been designed to meet the
Holdover requirements for a Stratum 3 Clock source as
called out in GR-1244-CORE, per Table 3-1 as
described in Sections 5.2 and 9.1 when used with
ACS8510 SETS.
Note: Other stability and output options are available.

This precision oscillator contains a quartz crystal which is susceptible to damage if handled
roughly or Dropped. Transportation and handling should be carefully performed. ESD
precautions should be taken. When stored, units should be kept in conductive containers and
only handled at properly grounded workstations by operators using proper ESD procedures.
We recommend hand placing and hand soldering units into a PCB. The soldering tip and
temperature should be appropriate for 60/40 type solder. If cleaning is required then a manual
brush cleaning with an appropriate solvent is recommended. If lead trimming is required, it may
be performed either manually or by machine methods. In either case care should be given to
prevent mechanical shock to the unit.
