DESIGN NOTES
The "Mini DIP
Serries" Digital Frequency Multiplier Modules developed
by Engineered Components Company have been designed to provide
precise T²L square wave outputs at selected clock frequencies
which are synchronized by square wave inputs at sub-harmonic
frequencies. These units can be synchronized by any sub-harmonic
frequency; if no synchronizing input is present, the unit
will free-run, providing a square wave output within ±2%
of the desired frequency. Temperature coefficient of this
free running frequency is less than ±500°ppm/°C.
Like all frequency multipliers, either digital or sinusoidal,
the amount of phase jitter in the output will increase as
higher orders of multiplication are used; although this
effect is smaller, lower orders of multiplication should
be considered in those applications where these slight time
variations are important.
The MDFDFMM-TTL is offered in thirty-eight (38) standard
clock frequencies from 2 MHz to 100 MHz. When tested under
the "Test Conditions" shown, output frequency is maintained
to eithin ±.005% of the nearest multiple of the input
frequency. Each of these modules is capable of driving up
to 10 T²L
loads.
These Digital Frequency Multiplier Modules are of hybrid
construction utilizing the proven technologies of active
integrated circuitry and of passive networks utilizing capacitive,
inductive and resistive elements. The MTBF on these modules,
when calculated per MIL-HDBK-217 for a 50°C ground fixed
environment, is in excess of 2 million hours.
These "Mini DIP Series" modules are packaged in an 8-pin
DIP housing, molded of flame-proof Diallyl Phthalate per
ASTM D 5948, Type SDG-F, and are fully encapsulated in epoxy
resin. Leads meet the solderablity requirements of MIL-STD-202,
Method 208. Corner standoffs on the housing on the thru-hole
lead version and lead design of the surface mount versions
provide positive standoff from the printed circuit board
to permit solder-fillet formation and flush cleaning of
solder-flux residues for improved reliability.
Marking consists of manufacturer's logo (EC²),
part number, pin one (1) identification and date code of
manufacture. All marking is applied by silk screen process
using white epoxy paint in accordance with MIL-STD-130,
to meet the permanency of identification required by MIL-STD-202,
Method 215.
