The signal inputs (I1-I2) are reproduced at the outputs (O1-O2), shifted in time by an amount determined by the device dash number (See Table). The delay lines function pletely independently of each other. ..

Prospect Ave. Clifton, NJ 07013 APPLICATION NOTES HIGH FREQUENCY RESPONSE The MDU28C tolerances are guaranteed for input pulse widths and periods greater than those specified in the test conditions. Although the device will function properly for pulse widths as small as 100% of the total delay and periods as small as 200% of the...
