FUNCTIONAL DESCRIPTION
The 1518-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 14-pin SMD with two pinout options.
Part numbers are constructed according to the scheme
shown at right. For example, 1518-101-500A is a 100ns,
50Ω delay line with pinout code A. Similarly, 1518-151-
501 a is 150ns, 500Ω delay line with standard pinout.

Notes:
TI represents nominal tap-to-tap delay increment
Tolerance on TD = ±5% or ±2ns, whichever is greater
Tolerance on TI = ±5% or ±1ns, whichever is greater
“N/A” indicates that delay is not available at this Z
