datasheet for 2775V by Nihon Dempa Kogyo Co., Ltd. (NDK)
Crystal Clock Oscillator
2785 Series
Programmable Type
n Model name
2785V Frequency stability of ±100 x 10–6.
n Application
l For compact mobile information equipment, such as a notebook PC,
mobile information terminal, and PC card
n Features
l PLL technology allows this crystal oscillator to support 1 to 125 MHz.
l With the adoption of frequency-writing technology, even the tightest
delivery deadline can be met.
l Automatic mounting by taping and IR reflow (lead-free) are possible.
l Compact and light. Dimensions and weight: 5.0 x 3.2 mm, 1.0 mm, and 0.06 g.

n How to Specify an Order
Example 1: When ordering a product with model name: 2785V, frequency: 80 MHz,
frequency stability: ±100 x 10–6, and power supply voltage: 5.0 V
When ordering our products, specify them with an “Ordering Code” that consists of the following:
Ordering Code: 2785V – 80.000000M – NSA5314A
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/).
