DSC2021

DSC2021 Low-Jitter Configurable Dual LVPECL-CMOS Oscillator General Description The DSC2021 series of high performance dual output oscillators utilize a proven silicon MEMS technology to provide excellent jitter and stability while incorporating additional device functionality. The two 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 DSC2021 has provision for up to eight user- defined pre-programmed, pin-selectable output frequency combinations. The DSC2021 is also equipped with independent pin-selectable output drive strengths for the CMOS output to reduce EMI and noise. DSC2021 is packaged in a 14-pin 3.2x2.5 mm QFN package and available in temperature grades from Ext. Commercial to Industrial.
