Description
The M/A-COM MAMUSM0008 is a 0 to 750 pS
variable delay line controlled by 4 complementary bit
pairs. It provides the user with 50 pS delay step
sizes for use in standard wireless applications. The
MAMUSM0008 is particularly useful in providing time
delay in the cancellation loops of feed-forward ampli-
fiers.

Control
Herein is described the control method for the
MAMUSM0008 Digital Delay Line. The information
will be aimed specifically at the use of the delay line
mounted on a M/A-COM test sample board. The
same theory and control scheme can be applied
directly to the component by itself.
This product allows the insertion of a variable
electrical delay between its two ports. The control
consists of four complimentary bit pairs (8 bits total).
Each pair is given a different letter, as shown in the
table to the right:.

The above table illustrates the method of controlling the bits for the desired delay in pico seconds. The hex and decimal representations are
included for programming purposes. “1” denotes 5 volts and “0” denotes 0 volts. A given delay line is set when bits 2 and bit 1 are set to 0
and 1 respectively. The given delay line is bypassed when the bits 2 and 1 are set to 1 and 0 respectively.
The “GND” pin on the test board header must be connected to the DC supply ground.
