FUNCTIONAL DESCRIPTION

PIN DESCRIPTIONS

The PDU1032H-series device is a 5-bit digitally programmable delay line.

The delay, TDA, from the input pin (IN) to the output pin (OUT) depends

on the address code (A4-A0) according to the following formula:

IN Signal Input

OUT Signal Output

A0-A4 Address Bits

TDA = TD0 + TINC * A

ENB Output Enable

VEE -5 Volts

where A is the address code, TINC is the incremental delay of the device,

GND Ground

and TD0 is the inherent delay of the device. The incremental delay is

specified by the dash number of the device and can range from 0.5ns through 20ns, inclusively. The

enable pin (ENB) is held LOW during normal operation. When this signal is brought HIGH, OUT is forced

into a LOW state. The address is not latched and must remain asserted during normal operation.

SERIES SPECIFICATIONS

• Total programmed delay tolerance: 5% or 2ns,

whichever is greater

• Inherent delay (TD0): 5.5ns typical for dash numbers

up to 5, greater for larger #’s

• Setup time and propagation delay:

Address to input setup (TAIS): 3.6ns

Disable to output delay (TDISO): 1.7ns typical

• Operating temperature: 0° to 70° C

• Temperature coefficient: 100PPM/°C (excludes TD0)

• Supply voltage VEE: -5VDC ± 5%

• Power Dissipation: 615mw typical (no load)

• Minimum pulse width: 20% of total delay
