1 / 6 page ______________________________________________________________________________________________________________________________________________ DSC2011 Page 1 MK-Q-B-P-D-12042602-2 Low-Jitter Configurable Dual CMOS Oscillator DSC2011 General Description The DSC2011 series of high performance dual output CMOS oscillators utilize a proven silicon MEMS technology to provide excellent jitter and stability while incorporating additional device functionality. The two CMOS outputs are controlled by separate supply voltages to allow for independent voltage level control. The frequencies of the outputs can be identical or independently derived from a common PLL frequency source. The DSC2011 has provision for up to eight user-defined pre-programmed, pin- selectable output frequency combinations. The DSC2011 is also equipped with independent pin-selectable output drive strengths for each output to reduce EMI and noise. DSC2011 is packaged in a 14-pin 3.2x2.5 mm QFN package and available in temperature grades from Ext. Commercial to Automotive. Block Diagram Features Low RMS Phase Jitter: <1 ps (typ) High Stability: ±10, ±25, ±50 ppm Wide Temperature Range o Automotive: -55° to 125° C o Ext. Industrial: -40° to 105° C o Industrial: -40° to 85° C o Ext. commercial: -20° to 70° C High Supply Noise Rejection: -50 dBc Two Independent CMOS Outputs Pin-Selectable Configurations o 2-bit Output Drive Strength o 3-bit Output Frequency Combinations Short Lead Times: 2 Weeks Wide Freq. Range: o CMOS Output: 2.3 to 170 MHz Miniature Footprint of 3.2x2.5mm Excellent Shock & Vibration Immunity o Qualified to MIL-STD-883 High Reliability o 20x better MTF than quartz oscillators Supply Range of 2.25 to 3.6 V Lead Free & RoHS Compliant Applications Consumer Electronics Storage Area Networks o SATA, SAS, Fibre Channel Passive Optical Networks o EPON, 10G-EPON, GPON, 10G-PON Ethernet o 1G, 10GBASE-T/KR/LR/SR, and FCoE HD/SD/SDI Video & Surveillance PCI Express |
