ORDERING INFORMATION

7.1

Ordering Part Number. The ordering part number is made up of an alphanumeric series

of 16 characters. Design-affected product options, identified by the parenthetic letter on

the Optional Parameters list (¶ 5.2a and b), are included within the device part number.

The Part Number breakdown is described as:

2101 R 100M0000 E B S

7.1.1

Model Number. The device model number is the four (4) digit number assigned to a

corresponding package and output combination per Table 1.

7.1.2

Design Pedigree. Class S designs correspond to letters “E” and “R” and are described in

paragraph 5.2a. Class B variants correspond to either letter “B” or “C” and are described in

paragraph 5.2a. Ruggedized COTS, using commercial grade components, correspond to letter

“D”.

7.1.2.1 Input Voltage. Voltage is the 15

7.1.3

Output Frequency. The nominal output frequency is expressed in the format as specified in

MIL-PRF-55310 utilizing eight (8) characters.
