1 / 2 page 1518 Doc #97030 DATA DELAY DEVICES, INC. 1 2/7/97 3 Mt. Prospect Ave. Clifton, NJ 07013 5-TAP SMD DELAY LINE TD/TR = 3 (SERIES 1518) FEATURES PACKAGES • 5 taps of equal delay increment • Delays to 200ns • Low profile • Epoxy encapsulated • Meets or exceeds MIL-D-23859C 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 (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, 50 Ω delay line with pinout code A. Similarly, 1518-151- 501 a is 150ns, 500 Ω delay line with standard pinout.
