The 8465, 8466, 8487, 8488 & 8509 have been
optimized to work with the Semtech Chip
ACS8510
SETS
to meet the requirements of Bell Core
specification GR-1244-CORE.
The 8465 & 8488 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.
The 8466, 8487 & 8509 have been designed to meet
the Holdover requirements for a Stratum 3E 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.
