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.
