FUNCTIONAL DESCRIPTION

PIN DESCRIPTIONS

The PDU108H-series device is a 3-bit digitally programmable delay line.

IN Signal Input

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

OUT Signal Output

the address code (A2-A0) according to the following formula:

A2 Address Bit 2

A1 Address Bit 1

TDA = TD0 + TINC * A

A0 Address Bit 0

ENB Output Enable

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

VEE -5 Volts

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

GND Ground

specified by the dash number of the device and can range from 0.5ns

through 50ns, 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 1ns,

whichever is greater

• Inherent delay (TD0): 2.8ns typical

• 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: 290mw typical (no load)

• Minimum pulse width: 25% of total delay
