FUNCTIONAL DESCRIPTION

PIN DESCRIPTIONS

The 3D3418 Programmable 8-Bit Silicon Delay Line product family

IN

Signal Input

consists of 8-bit, user-programmable CMOS silicon integrated

OUT Signal Output

circuits. Delay values, programmed either via the serial or parallel

MD Mode Select

interface, can be varied over 255 equal steps ranging from 250ps

AE Address Enable

to 7.5ns inclusively. Units have a typical inherent (address 0)

P0-P7 Parallel Data Input

delay of 20ns (See Table 1). The input is reproduced at the output

SC Serial Clock

without inversion, shifted in time as per user selection. The

SI

Serial Data Input

3D3418 is CMOS-compatible, and features both rising- and

SO Serial Data Output

falling-edge accuracy.

VDD +3.3 Volts

GND Ground

The all-CMOS 3D3418 integrated circuit has been designed as a

reliable, economic alternative to hybrid TTL programmable delay lines. It is offered in a standard 16-pin

auto-insertable DIP and a space saving surface mount 16-pin SOIC.
