FUNCTIONAL DESCRIPTION
The 1520-series device is a fixed, single-input, ten-output,
passive delay line. The signal input (IN) is reproduced at the
outputs (T1-T10) in equal increments. The delay from IN to T10
(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
20% of T
D
, and the 3dB bandwidth is given by 1.75 / T
D
. The
device is available in a 14-pin DIP (1520) or a 14-pin SMD
(1520S), and a wide range of pinouts may be specified.
Part numbers are constructed according to the scheme shown
at right. For example, 1520C-101-500B is a 290 mil DIP,
100ns, 50
delay line with pinout code B. Similarly, 1520SB-
201-251 is a 240 mil SMD, 200ns, 250
delay line with
standard pinout.
