FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
The DDU12H-series device is a 10-tap digitally buffered delay line. The
IN Signal Input
signal input (IN) is reproduced at the outputs (T1-T10), shifted in time by
T1-T10 Tap Outputs
an amount determined by the device dash number (See Table). For dash VEE -5 Volts
numbers less than 20, the total delay of the line is measured from T1 to
GND Ground
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.
