Crystal Clock Oscillator
NZ2520S Series
■
Model name
NZ2520SB Overall frequency tolerance of ±20 x 10
–6
.
■
Application
● For wireless LAN, UWB, and WiMAX
● For compact mobile information equipment, such as DVC, DSC, notebook PC,
and PDA
■
Features
● Compact and light. Dimensions : 2.5 x 2.0 x 0.9 mm, weight : 0.02 g.
● This crystal clock oscillator can support low frequencies (from 1.5 MHz); an
achievement not easy for other crystal oscillators of the same size to equal.
● Automatic mounting by taping and IR reflow (lead–free) are possible.
● Lead–free.
Absolute maximum rating

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: NZ2520SB, frequency: 20 MHz, overall frequency tolerance: ±20 x 10
–6
,
and supply voltage: 1.8 V
Ordering Code: NZ2520SB – 20.000000M – NSA3412D
Example 2: When ordering a product with model name: NZ2520SB, frequency: 20 MHz, overall frequency tolerance: ±20 x 10
–6
,
and supply voltage: 3.3 V
Ordering Code: NZ2520SB – 20.000000M – NSA3415D
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/).
