n How to Specify an Order
Example 1: When ordering a product with model name: 2775Y, frequency: 68 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}
Ordering Code: 2775Y – 68.000000M – NSA5312A
Model name – Frequency (up to 9 digits) M– Number for specifying an order
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/).
