DSC1003DL5-025.0000

**1.8~3.3V** 

## **General Description** 

## **Features** 

- Frequency Range:  1 to 150MHz 

The DSC1003 is a silicon MEMS based CMOS oscillator offering excellent jitter and stability performance over a wide range of supply voltages and temperatures. The device operates from 1 to 150MHz with supply voltages between 1.8 to 3.3 Volts and extended temperatures from -40ºC to 105ºC. The DSC1003 has the same functionality and performance as the DSC1001 but with greater output drive (CL< 25pf). 

The DSC1003 incorporates an all silicon resonator that is extremely robust and nearly immune to stress related fractures, common to crystal based oscillators.  Without sacrificing the performance and stability required of today’s systems, a crystal-less design allows for a higher level of reliability, making the DSC1003 ideal for rugged, industrial, and portable applications where stress, shock, and vibration can damage quartz crystal based systems. 

- Exceptional Stability over Temperature `o` ±10 PPM , ±25 PPM, ±50 PPM 

- Operating voltage 

- 1.7 to 3.6V 

- Operating Temperature Range `o` Ext. Industrial -40ºC to 105ºC `o` Industrial -40ºC to 85ºC `o` Ext. Commercial -20ºC to 70ºC `o` Commercial 0ºC to 70ºC 

- Low Operating and Standby Current `o` 6mA Operating (40MHz) `o` 15uA Standby 

- Ultra Miniature Footprint 

   - 2.5 x 2.0 x 0.85 mm 

   - `o` 3.2 x 2.5 x 0.85 mm `o` 5.0 x 3.2 x 0.85 mm `o` 7.0 x 5.0 x 0.85 mm 

- Excellent Shock and Vibration Resistance 

- Lead Free, RoHS & Reach SVHC Compliant 

Available in industry standard packages, the DSC1003 can be “dropped-in” to the same PCB footprint as standard crystal oscillators. 

## **Block Diagram** 

## **Benefits** 

- Pin for pin “drop in” replacement for industry standard oscillators 

- Semiconductor level reliability, significantly higher than quartz 

- Short mass production lead-times 

- Longer Battery Life / Reduced Power 

- Compact Plastic package  Cost Effective
