FUNCTIONAL DESCRIPTION

The 3D3418 Programmable 8-Bit Silicon Delay Line product family consists of 8-bit, user-programmable CMOS silicon integrated circuits. Delay values, programmed either via the serial or parallel interface, can be varied over 255 equal steps ranging from 250ps to 7.5ns inclusively. Units have a typical inherent (address 0) delay of 20ns (See Table 1). The input is reproduced at the output without inversion, shifted in time as per user selection. The 3D3418 is CMOS-compatible, and features both rising- and falling-edge accuracy.
