DESIGN NOTES

The "DIP series" FAST 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), OUT will be a

constant "1" (high). Whenever the enable input goes low, OUT goes low after a one-half

cycle delay. When enable input returns to high, OUT is forced high one-half cycle later.

(Note: The output buffers will add one propagation delay to all times.)

These FAST 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 500°C ground fixed environment, is in excess of 5

million hours.

The FSWG-TTL is offered in thirty (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 +700°C.

These "DIP Series" modules are packaged in a 14-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 solderability requirements of MIL-STD-202, Method 208.

Corner standoffs on the housing of the thru-hole lead version and the 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 TTL FAST toggle-type gate driving the input and one FAST

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.
