SSFGSWG-TTL-30T - Engineered Components Company

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.
