FUNCTIONAL DESCRIPTION
The 1516-series device is a fixed, single-input, five-
output, passive delay line. The signal input (IN) is
reproduced at the outputs (T1-T5) in equal increments.
The delay from IN to T5 (T
D
) and the characteristic
impedance of the line (Z) are determined by the dash
number. The rise time (T
R
) of the line is 30% of T
D
, and
the 3dB bandwidth is given by 1.05 / T
D
. The device is
available in a 8-pin DIP (1516) or a 8-pin SMD (1516S),
and a wide range of pinouts may be specified.
Part numbers are constructed according to the scheme
shown at right. For example, 1516C-101-500B is a 290
mil DIP, 100ns, 50Ω delay line with pinout code B.
Similarly, 1516SB-151-501 is a 240 mil SMD, 150ns,
500Ω delay line with standard pinout.
