The "Space Saver Series" Gated Square Wave Generator modules
developed by Engineered Components Company have been de-
signed to provide a T2L level square wave output at frequencies from
2 MHz to 100 MHz. These generators are both keyable and
synchronizable, producing a continuous output train as long as a zero
(low) is maintained at the enable input. As long as the enable input is
a "1" (high), OUT1 will be a constant "1" (high) and OUT2 will be a
constant "0" (low). Whenever the enable input goes low, OUT2 goes
high immediately. OUT1 and OUT2 go low together after a one-half
cycle delay and, thereafter run in phase. When enable input returns
to high, OUT2 is forced low immediately and OUT1 is forced high one-
half cycle later. (Note: The output buffers will add one propagation
delay to all times).
These Gated Square Wave Generator 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 50o C ground fixed environ-
ment, is in excess of 3 million hours.
The SSFGSWG-TTL is offered in 30 different frequencies
from 2 MHz to 100 MHz. Output frequencies are controlled to
within ±2% and have a temperature coefficient of less than -500
ppm/oC over the operating temperature range of 0 to +70oC.
These "Space Saver Series" modules are packaged in an
8-pin housing, molded of flame-proof Diallyl Phthalate per MIL-
M-14, Type SDG-F, and are fully encapsulated in epoxy resin.
Thru-hole, J, Gull Wing or Tucked Lead configurations are
available on these modules (see Part Number Table note to
specify). Leads meet the solderability requirements of MIL-
STD-202, Method 208. Corner standoffs on the housing of 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 name, logo (EC2), part
number, terminal 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 perma-
nency of identification required by MIL-STD-202, Method 215.
