## **General Description** 

The DSC1103 and DSC1123 series of high performance oscillators utilizes a proven silicon MEMS technology to provide excellent jitter and stability over a wide range of supply voltages and temperatures. By eliminating the need for quartz or SAW technology, MEMS oscillators significantly enhance reliability and accelerate product development, while meeting stringent clock performance criteria for a variety of communications, storage, and networking applications. 

DSC1103 has a standby feature allowing it to completely power-down when EN pin is pulled low. For DSC1123, only the outputs are disabled when EN is low. Both oscillators are available in industry standard packages, including the smallest 2.5 mm x 2.0 mm, and are drop-in replacements for standard 6-pin LVDS crystal oscillators. 

- 7.0 mm x 5.0 mm 

- Excellent Shock and Vibration Immunity 

## **Block Diagram** 

- Qualified to MIL-STD-883 

- High Reliability 

- 20x better MTF than quartz-based devices 

- Low Current Consumption 

- Supply Range of 2.25V to 3.63V 

- Standby and Output Enable Functions 

- Lead Free and RoHS-Compliant 

## **Applications** 

- Storage Area Networks

**Note 1:** The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction temperature, and the thermal resistance from junction to air (i.e., TA, TJ, JA). Exceeding the maximum allowable power dissipation will cause the device operating junction temperature to exceed the maximum +150°C rating. Sustained junction temperatures above +150°C can impact the device reliability.

## **Note the following details of the code protection feature on Microchip devices:** 

- Microchip products meet the specification contained in their particular Microchip Data Sheet. 

- Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. 

- There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. 

- Microchip is willing to work with the customer who is concerned about the integrity of their code. 

- Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.” 

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
