FUNCTIONAL DESCRIPTION
The 2214-series device is a fixed, single-input, twenty-output, passive delay line. The signal input (IN) is
reproduced at the outputs (T1-T20) in equal increments. The delay from IN to T20 (T
D
) is given by the
device dash number. The characteristic impedance of the line is given by the letter code that follows the
dash number (See Table). The rise time (T
R
) of the line is 10% of T
D
, and the 3dB bandwidth is given by
3.5 / T
D
.
