ADS5444_08 Datasheet, PDF (1/1 Pages) Texas Instruments – 13-BIT 250 MSPS ANALOG-TO-DIGITAL CONVERTER

Crystal Clock Oscillator ^NEW
NZ2520S Series
n Model name
NZ2520SB Frequency stability of ±20 x 10^–6.
n Application
l For wireless LAN, UWB, and WIMAX
l For compact mobile information equipment, such as DVC, DSC, notebook PC, and PDA
n Features
l Size: A minimum-size crystal clock oscillator with dimensions of 2.5 x 2.0 mm.
l Thickness: Ultra-thin with a thickness of 0.9 mm.
l Weight: Weighs only 0.02 g, giving unparalleled light-weight.
l 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.
l Automatic mounting by taping and IR reflow (lead-free) are possible.
l Lead-free.

n 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,
frequency stability: ±20 x 10^–6, and power supply voltage: 1.8 V
Ordering Code: NZ2520SB – 20.000000M – NSA3412D
Example 2: When ordering a product with model name: NZ2520SB, frequency: 20 MHZ,
frequency stability: ±20 x 10^–6, and power 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/).
