DSC1033 3.3V Low-Power CMOS Oscillator General Description Features The DSC1033 is a 3.3V fixed frequency MEMS based PureSilicon™ Oscillator. It can be factory programmed to any frequency from 1 to 150MHz. The DSC1033 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 DSC1033 ideal for rugged, industrial, and portable applications where stress, shock, and vibration can damage quartz crystal based systems. Available in industry standard packages, the DSC1033 can be “dropped-in” to the same PCB footprint as standard crystal oscillators.

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 EN is asserted) are identical values. 3. See typical cycle to cycle jitter graph for frequency dependence. _____________________________________________________________________________________________________________________________ _________________ DSC1033 Page 2 MK-Q-B-P-D-031809-01-8 3.3V DSC1033 Low-Power CMOS Oscillator Nominal Performance Characteristics 3.3V Characteristics Supply Current Standby Current 1 Ta = 25°C 1pF 8pF 15pF Standby Current (µA) Supply Current (mA) 16 12 8 4 0 -40°C 0.8 0.6 0.4 0.2 50 100 Frequency (MHz) 150 0 Rise Time 50 100 Frequency (MHz) 150 Fall Time 2 2 -40°C 25°C 85°C -40°C 1.5 Fall Time (ns) Rise Time (ns) 85°C 0 0 1 0.5 0 25°C 85°C 1.5 1 0.5 0 0 50 100 Frequency (MHz) 150 0 Period Jitter 50 100 Frequency (MHz) 150 Cycle to Cycle Jitter 40 200 25°C 25°C 30 150 Jitter (ps) RMS Jitter (ps) 25°C 20 100 10 50 0 0 0 50 100 Frequency (MHz) 150 0 50 100 Frequency (MHz) 150 _____________________________________________________________________________________________________________________________ _________________ DSC1033 Page 3 MK-Q-B-P-D-031809-01-8 3.3V DSC1033 Low-Power CMOS Oscillator Output Waveform tR tF VOH Output VOL tEN 1/fo tDA VIH Standby# VIL Standby Function Standby# Output (pin 1) (pin 3) Hi Level Output ON Open (no connect) Output ON Low Level High Impedance Test Circuit IDD VDD 0.01uF 4 3 1 2 15pF *VSD *VSD = Standby# Logic Level Input _____________________________________________________________________________________________________________________________ _________________ DSC1033 Page 4 MK-Q-B-P-D-031809-01-8 3.3V DSC1033 Low-Power CMOS Oscillator Board Layout (recommended) Solder Reflow Profile 20-40 Sec Se 3C / 217°C 200°C 60-150 Sec S 6C/ ax cM Se 3C / 25°C 60-180 Sec Pre heat 8 min max Reflow x. 150°C Ma . ec Temperature (°C) cM ax . 260°C Cool MSL 1 @ 260°C refer to JSTD-020C Ramp-Up Rate (200°C to Peak Temp) 3°C/Sec Max.
