FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
The 2020- and 2021-series devices are fixed, single-input, single-output,
passive delay lines. The signal input (IN) is reproduced at the output (OUT),
shifted by a time (TD) given by the device dash number. The characteristic
impedance of the lines is nominally 50 ohms. The rise time (TR) of the lines
is no more than 1ns, resulting in a 3dB bandwidth of at least 350MHz.
