Example 1: When ordering a product with model name: 2775Y, frequency: 68 MHz,
frequency stability: ±50 x 10
–6
, and power supply voltage: 3.3 V
When ordering our products, specify them with an “Ordering Code” that consists of the following:
Ordering Code: 2775Y – 68.000000M – NSA5312B
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/).
