DDU66F-125

Total delay 125 +/-6.5ns,5-TAP, TTL-interfaced fixed delay line

FUNCTIONAL DESCRIPTION

The DDU66F-series device is a 5-tap digitally buffered delay line. The signal input IN is reproduced at the outputs T1-T5, shifted in time by an amount given by the device dash number. For dash numbers less than 25, the total delay of the line is measured from T1 to T5, with the nominal value given by the dash number. The nominal tap-to-tap delay increment is given by 1/4 of this number. The inherent delay from IN to T1 is nominally 3.5ns. For dash numbers greater than or equal to 25, the total delay of the line is measured from IN to T5, with the nominal value

given by the dash number. The nominal tap-to-tap delay increment is given by 1/5 of this number.
