5-TAP, ECL-INTERFACED
FIXED DELAY LINE
(SERIES DDU12H)
FEATURES
PACKAGES
Ten equally spaced outputs
Fits in 300 mil 32-pin DIP socket
Input & outputs fully 10KH-ECL interfaced & buffered
FUNCTIONAL DESCRIPTION
The DDU12H-series device is a 10-tap digitally buffered delay line. The
signal input (IN) is reproduced at the outputs (T1-T10), shifted in time by
an amount determined by the device dash number (See Table). For dash
numbers less than 20, the total delay of the line is measured from T1 to
T10. The nominal tap-to-tap delay increment is given by one-ninth of the
total delay, and the inherent delay from IN to T1 is nominally 1.5ns. For dash numbers greater than or
equal to 20, the total delay of the line is measured from IN to T10. The nominal tap-to-tap delay increment
is given by one-tenth of this number.
