PACKAGES IN Signal Input T1-T5 Tap Outputs GND Ground Note: Standard pinout shown Alt. pinout available FUNCTIONAL DESCRIPTION The 1518-series device is a fixed, single-input, fiveoutput, passive delay line. The signal input (IN) is reproduced at the outputs (T1-T5) in equal increments. The delay from IN to T5 (TD) and the characteristic impedance of the line (Z) are determined by the dash number. The rise time (TR) of the line is 30% of TD, and the 3dB bandwidth is given by 1.05 / TD. 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, 1518-151501 a is 150ns, 500Ω delay line with standard pinout.
