The 6661, 6662, 6663, 6664 have been optimized to
work with the Semtech Chip
the requirements of Bell Core specification GR-1244-
CORE and ITU G.813.
The 6664 in particular has been designed to meet
the stringent 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 9.1.1.
All four units have been designed to meet the
0.05 ppm over
Frequency vs Supply requirement of
5% change in Supply from a minimum of
+3.135 Vdc to a maximum of +5.5 Vdc.
Other stability and output options are available.
