TRIPLE, ECL-INTERFACED

FIXED DELAY LINE

(SERIES MDU13H)

FEATURES

PACKAGES

• 

Three independent delay lines

• 

Fits standard 16-pin DIP socket

• 

Auto-insertable

• 

Input & outputs fully 10KH-ECL interfaced & buffered

FUNCTIONAL DESCRIPTION

The MDU13H-series device is a 3-in-1 digitally buffered delay line.  The

signal inputs (I1-I3) are reproduced at the outputs (O1-O3), shifted in time

by an amount determined by the device dash number (See Table).  The

delay lines function completely independently of each other.

APPLICATION NOTES

HIGH FREQUENCY RESPONSE

The MDU13H tolerances are guaranteed for

input pulse widths and periods greater than those

specified in the test conditions.  Although the

device will function properly for pulse widths as

small as 50% of the total delay and periods as

small as 100% of the total delay (for a symmetric

input), the delays may deviate from their values

at low frequency.  However, for a given input

condition, the deviation will be repeatable from

pulse to pulse.  Contact technical support at Data

Delay Devices if your application requires device

testing at a specific input condition.

POWER SUPPLY BYPASSING

The MDU13H relies on a stable power supply to

produce repeatable delays within the stated

tolerances.  A 0.1uf capacitor from VEE to GND,

located as close as possible to the VEE pin, is

recommended.  A wide VEE trace and a clean

ground plane should be used.
