How to Specify an Order
When ordering our products, specify them with an “Ordering Code” that consists of the following:
Model name – Frequency (up to 9 digits) M – Number for specifying an order
Example 1: When ordering a product with model name: NZ2520SD, frequency: 20 MHz, overall frequency tolerance: ±20 x 10
–6
,
and supply voltage: 1.8 V
Ordering Code: NZ2520SD – 20.000000M – NSA3446D
Example 2: When ordering a product with model name: NZ2520SD, frequency: 20 MHz, overall frequency tolerance: ±20 x 10
–6
,
and supply voltage: 3.3 V
Ordering Code: NZ2520SD – 20.000000M – NSA3449D
If you have any queries concerning our standard frequencies and numbers for specifying orders, please contact our sales representatives
or visit our homepage (http://www.ndk.com/).
