FEATURES

10 taps of equal delay increment IN Signal Input T1-T10 Tap Outputs GND Ground Note: Standard pinout shown Other pinouts available Delays to 1000ns Low profile Epoxy encapsulated Meets or exceeds MIL-D-23859C FUNCTIONAL DESCRIPTION The 1520-series device is a fixed, single-input, ten-output, passive delay line. The signal input (IN) is reproduced at the outputs (T1-T10) in equal increments. The delay from IN to T10 (TD) and the characteristic impedance of the line (Z) are determined by the dash number. The rise time (TR) of the line is 20% of TD, and the 3dB bandwidth is given by 1.75 / TD. The device is available in a 14-pin DIP (1520) or a 14-pin SMD (1520S), and a wide range of pinouts may be specified. Part numbers are constructed according to the scheme shown at right. For example, 1520C-101-500B is a 290 mil DIP, 100ns, 50Ω delay line with pinout code B. Similarly, 1520SB- 201-251 is a 240 mil SMD, 200ns, 250Ω delay line with standard pinout.
