n How to Specify an Order
Example 1: When ordering a product with model name: 2560TK, frequency: 20 MHz,
When ordering our products, specify them with an “Ordering Code” that consists of the following: frequency stability: ±100 x 10–6, and power supply voltage: 3.3 V
Model name – Frequency (up to 9 digits) M– Number for specifying an order
Ordering Code: 2560TK – 20.000000M – NSA3285C
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/).
