n How to Specify an Order
Example 1: When ordering a product with model name: 2725Z, frequency: 20 MHz,
frequency stability: ±100 x 10–6, and power supply voltage: 1.8 V
When ordering our products, specify them with an “Ordering Code” that consists of the following:
Ordering Code: 2725Z – 20.000000M – NSA6297A
–
–
M
Number for specifying an order
Model name Frequency (up to 9 digits)
