## **General Description** ## **Features** - Frequency Range: 1 to 150MHz The DSC1001 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 temperature ranges up to -40ºC to 105ºC. The DSC1001 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 DSC1001 ideal for rugged, industrial, and portable applications where stress, shock, and vibration can damage quartz crystal based systems. Available in industry standard packages, the DSC1001 can be “dropped-in” to the same PCB footprint as standard crystal oscillators. - Exceptional Stability over Temperature `o` ±10 PPM, ±25 PPM, ±50 PPM - Operating voltage - 1.7 to 3.6V - Operating Temperature Range - 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` 5mA 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 - MIL-STD 883 Shock and Vibration Resistant - Pb Free, RoHS, Reach SVHC Compliant - AEC-Q100 Reliability Qualified ## **Benefits** ## **Block Diagram** - Pin for pin “drop in” replacement for industry standard oscillators - Semiconductor level reliability, significantly higher than quartz **==> picture [511 x 172] intentionally omitted <==** **----- Start of picture text -----**

~~—Saeee~~| |Notes:| |1.
Absolute maximum ratings are those values beyond which the safety of the device cannot be guaranteed. The device should not be| |operated beyond these limits.| 2. tSU is time to stable output frequency after VDD is applied. tSU and tEN (after Standby# is asserted high) are identical values. 3. Measured over 50k clock cycles.
