FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
The 1514-series device is a fixed, single-input, single-output, passive
IN
Signal Input
delay line. The signal input (IN) is reproduced at the output (OUT), shifted
OUT Signal Output
by a time (T
D
) given by the device dash number. The characteristic
GND Ground
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 20% of T
D
, and the 3dB bandwidth is given by 1.75 /
T
D
.
