DESIGN NOTES

The "Space Saver Series" Gated Square Wave Generator modules developed by

Engineered Components Company have been designed 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 50°C ground fixed environment, 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/°C over the operating temperature range of 0 to +70°C.

These "Space Saver Series" modules are packaged in an 8-pin housing, molded of

flame-proof Diallyl Phthalate per ASTM D 5948, 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 permanency of identification

required by MIL-STD-202, Method 215.

TEST CONDITIONS

1. All measurements are made at 25°C.

2. Vcc supply voltage is maintained at 5.0V DC.

3. All units are tested using a Schottky toggle-type gate driving the input and one

Schottky T²L load at the output.

OPERATING SPECIFICATIONS

*Output frequency will increase or decrease less than 1% for a respective increase or

decrease of 5% in supply voltage.
